Problem 1:
The Kerwoods’ bill was $58.65. They left a 15% tip. How much did they pay altogether?
Step 1: Find 15% of $58.65
→ 15% = 0.15
→ 0.15 × 58.65 = ?
Let’s calculate:
0.15 × 58.65
= (0.10 × 58.65) + (0.05 × 58.65)
= 5.865 + 2.9325
= 8.7975 → round to nearest cent →
$8.80
Step 2: Add tip to original bill
→ 58.65 + 8.80 =
$67.45
✔ Final Answer for #1:
$67.45

Problem 2:
Ms. Acton spent $205.60 at Target. Sales tax is 6%. What was her final bill?
Step 1: Find 6% of $205.60
→ 6% = 0.06
→ 0.06 × 205.60 = ?
Calculate:
0.06 × 205.60
= (0.06 × 200) + (0.06 × 5.60)
= 12 + 0.336
= 12.336 → round to nearest cent →
$12.34
Step 2: Add tax to original amount
→ 205.60 + 12.34 =
$217.94
✔ Final Answer for #2:
$217.94

Problem 3:
Macy’s has a 35% off special. Sara bought $124.50 worth of items. What’s the final bill after discount?
Step 1: Find 35% of $124.50
→ 35% = 0.35
→ 0.35 × 124.50 = ?
Calculate:
0.35 × 124.50
= (0.30 × 124.50) + (0.05 × 124.50)
= 37.35 + 6.225
= 43.575 → round to nearest cent →
$43.58
Step 2: Subtract discount from original price
→ 124.50 - 43.58 =
$80.92
✔ Final Answer for #3:

→ 20% = 0.20
→ 0.20 × 52.35 =
$10.47
Step 2: Add tip to bill
→ 52.35 + 10.47 =
$62.82
Step 3: Divide by 4 people
→ 62.82 ÷ 4 =
$15.705 → round to nearest cent →

Ms. Stoner bought a computer for $1,150. Sales tax is 7.5%. What was total purchase?
Step 1: Find 7.5% of $1,150
→ 7.5% = 0.075
→ 0.075 × 1150 = ?
Calculate:
0.075 × 1150
= (0.07 × 1150) + (0.005 × 1150)
= 80.5 + 5.75
=
86.25
Step 2: Add tax to price
→ 1150 + 86.25 =

- Carrots: $2.25
- Flowers: $9.95
Sales tax is 5%. What will Maria pay altogether? *(Note: Probably typo — should be Vicky, not Maria. We’ll assume it’s Vicky.)*
Step 1: Add up all purchases
→ 3.50 + 2.25 + 9.95 = ?
3.50 + 2.25 = 5.75
5.75 + 9.95 =
$15.70
Step 2: Find 5% of $15.70
→ 5% = 0.05
→ 0.05 × 15.70 =
$0.785 → round to nearest cent →
$0.79
Step 3: Add tax
→ 15.70 + 0.79 =
$16.49
