Tax, Tip, and Discount Word Problems Worksheet | Grade1to6 - Free Printable

Let’s solve each row step by step. We’ll calculate:

- 10% of the bill → just move decimal one place left (or multiply by 0.1)
- 5% (sales tax) → half of 10%
- 15% → 10% + 5%
- 20% → double the 10%

We’ll go row by row and check our math carefully.

---

Row 1: Bill = $12.20

- 10% = $12.20 × 0.1 = $1.22
- 5% = half of $1.22 = $0.61
- 15% = $1.22 + $0.61 = $1.83
- 20% = $1.22 × 2 = $2.44

✔ Check: All look correct.

---

Row 2: Bill = $18.30

- 10% = $18.30 × 0.1 = $1.83
- 5% = half of $1.83 = $0.915 → round to nearest cent? Usually we keep two decimals for money → $0.92? Wait — let’s be precise.

Actually, in real life, we often round to the nearest cent. But since this is a math worksheet, maybe they expect exact values? Let’s see what the example did.

In the example: $50 × ½ = $2.5 → so they used exact halves.

So for $18.30:

- 10% = $1.83
- 5% = $1.83 ÷ 2 = $0.915 → but money doesn’t have fractions of cents. Hmm.

Wait — looking at the example again: “$50 × ½ = $2.5” — that’s fine because it ends in .5.

But $18.30 ÷ 2 = $9.15 → then 5% is half of 10%, which is half of $1.83 → $0.915 → which is not a valid money amount.

This suggests we should probably round to the nearest cent when needed.

But let’s check the problem’s own examples:

They show:
“Find 5% on $50 → $50 × 0.½ = $2.5” → so they’re using 0.5 as multiplier.

Actually, 5% = 0.05, so better to do direct multiplication to avoid confusion.

Let me recalculate using decimals properly:

Better method:

- 10% = bill × 0.1
- 5% = bill × 0.05
- 15% = bill × 0.15
- 20% = bill × 0.2

That’s more accurate and avoids rounding errors from halving.

Let’s redo with this method.

---

Row 1: $12.20

- 10% = 12.20 × 0.1 = 1.22
- 5% = 12.20 × 0.05 = 0.61
- 15% = 12.20 × 0.15 = 1.83
- 20% = 12.20 × 0.2 = 2.44

Same as before — good.

---

Row 2: $18.30

- 10% = 18.30 × 0.1 = 1.83
- 5% = 18.30 × 0.05 = 0.915 → now, how to handle? In real life, you’d round to $0.92, but let’s see if the worksheet expects exact or rounded.

Looking back at the example: They wrote “$50 × ½ = $2.5” — which is exact.

But $18.30 × 0.05 = 0.915 — which is 91.5 cents — not possible.

Perhaps we should always round to the nearest cent.

Standard practice: Round to nearest cent (two decimal places).

So 0.915 → rounds to 0.92

Then:

- 15% = 18.30 × 0.15 = 2.745 → rounds to 2.75
- 20% = 18.30 × 0.2 = 3.66 → exact

But wait — if we use 10% + 5%: 1.83 + 0.92 = 2.75 — matches.

So yes, we should round to nearest cent when needed.

I think for consistency, we’ll calculate using multiplication and round to two decimal places where necessary.

Let’s proceed with that.

---

Row 2: $18.30

- 10% = 18.30 × 0.1 = 1.83
- 5% = 18.30 × 0.05 = 0.915 → 0.92 (rounded)
- 15% = 18.30 × 0.15 = 2.745 → 2.75 (rounded)
- 20% = 18.30 × 0.2 = 3.66

✔ Good.

---

Row 3: $80.00

- 10% = 80 × 0.1 = 8.00
- 5% = 80 × 0.05 = 4.00
- 15% = 80 × 0.15 = 12.00
- 20% = 80 × 0.2 = 16.00

Easy — no rounding needed.

---

Row 4: $5.75

- 10% = 5.75 × 0.1 = 0.575 → round to 0.58
- 5% = 5.75 × 0.05 = 0.2875 → round to 0.29
- 15% = 5.75 × 0.15 = 0.8625 → round to 0.86
- 20% = 5.75 × 0.2 = 1.15 → exact

Check: 10% + 5% = 0.58 + 0.29 = 0.87 — but 15% calculated directly is 0.8625 → rounds to 0.86. Slight discrepancy due to rounding intermediate steps.

To avoid this, better to calculate each percentage directly from the bill, not from other percentages.

So:

- 15% = 5.75 × 0.15 = 0.8625 → 0.86
- 20% = 5.75 × 0.2 = 1.15

And for 5%: 5.75 × 0.05 = 0.2875 → 0.29

10%: 0.575 → 0.58

It’s okay if 10% + 5% ≠ 15% exactly due to rounding — that happens in real life too.

We’ll go with direct calculation and round each to nearest cent.

---

Row 4: $5.75

- 10% = 0.58
- 5% = 0.29
- 15% = 0.86
- 20% = 1.15

---

Row 5: $6.99

- 10% = 6.99 × 0.1 = 0.699 → 0.70
- 5% = 6.99 × 0.05 = 0.3495 → 0.35
- 15% = 6.99 × 0.15 = 1.0485 → 1.05
- 20% = 6.99 × 0.2 = 1.398 → 1.40

Check: 0.70 + 0.35 = 1.05 — matches 15%. Good.

---

Row 6: $2.90

- 10% = 2.90 × 0.1 = 0.29
- 5% = 2.90 × 0.05 = 0.145 → 0.15 (since 0.145 rounds up)
- 15% = 2.90 × 0.15 = 0.435 → 0.44
- 20% = 2.90 × 0.2 = 0.58

Check: 0.29 + 0.15 = 0.44 — matches 15%. Perfect.

---

Row 7: $66.25

- 10% = 66.25 × 0.1 = 6.625 → 6.63 (round up)
- 5% = 66.25 × 0.05 = 3.3125 → 3.31
- 15% = 66.25 × 0.15 = 9.9375 → 9.94
- 20% = 66.25 × 0.2 = 13.25

Check: 6.63 + 3.31 = 9.94 — matches. Good.

---

Row 8: $4.50

- 10% = 4.50 × 0.1 = 0.45
- 5% = 4.50 × 0.05 = 0.225 → 0.23 (round up)
- 15% = 4.50 × 0.15 = 0.675 → 0.68
- 20% = 4.50 × 0.2 = 0.90

Check: 0.45 + 0.23 = 0.68 — matches. Good.

---

Row 9: $74.80

- 10% = 74.80 × 0.1 = 7.48
- 5% = 74.80 × 0.05 = 3.74
- 15% = 74.80 × 0.15 = 11.22 → 11.22 (exact)
- 20% = 74.80 × 0.2 = 14.96

All exact or clean — no rounding issues.

---

Row 10: $20.25

- 10% = 20.25 × 0.1 = 2.025 → 2.03 (round up)
- 5% = 20.25 × 0.05 = 1.0125 → 1.01
- 15% = 20.25 × 0.15 = 3.0375 → 3.04
- 20% = 20.25 × 0.2 = 4.05

Check: 2.03 + 1.01 = 3.04 — matches 15%. Perfect.
