Let’s solve each problem one by one. We’ll calculate the discount amount first, then subtract it from the original price to get the sale price.

Problem 1:
Original Price = $212
Discount = 39%
Step 1: Find 39% of 212
→ 39% = 0.39
→ 0.39 × 212 = ?
Let’s compute:
0.39 × 200 = 78
0.39 × 12 = 4.68
Total = 78 + 4.68 =
82.68
Step 2: Subtract discount from original price
212 - 82.68 =
129.32
✔ Discount Sale Price =
$129.32

Problem 2:
Original Price = $812
Discount = 13%
Step 1: Find 13% of 812
→ 0.13 × 812
Break it down:
0.10 × 812 = 81.2
0.03 × 812 = 24.36
Total = 81.2 + 24.36 =
105.56
Step 2: Subtract
812 - 105.56 =
706.44
✔ Discount Sale Price =
$706.44

Problem 3:
Original Price = $111
Discount = 49%
Step 1: Find 49% of 111
→ 0.49 × 111
Think of it as (50% - 1%) of 111
50% of 111 = 55.5
1% of 111 = 1.11
So 49% = 55.5 - 1.11 =
54.39
Step 2: Subtract
111 - 54.39 =
56.61
✔ Discount Sale Price =
$56.61
---
Problem 4:
Original Price = $291
Discount = 19%
Step 1: Find 19% of 291
→ 0.19 × 291
Break into:
0.20 × 291 = 58.2 → that’s 20%
Minus 1% of 291 = 2.91
So 19% = 58.2 - 2.91 =
55.29
Step 2: Subtract
291 - 55.29 =
235.71
✔ Discount Sale Price =
$235.71

Problem 5:
Original Price = $315
Discount = 29%
Step 1: Find 29% of 315
→ 0.29 × 315
Break into:
0.30 × 315 = 94.5 → that’s 30%
Minus 1% of 315 = 3.15
So 29% = 94.5 - 3.15 =
91.35
Step 2: Subtract
315 - 91.35 =
223.65
✔ Discount Sale Price =
$223.65

Final Answer:
1. $129.32
2. $706.44
3. $56.61
4. $235.71
5. $223.65
