Explanation:

Problem 3 (Shakira's Clothing Purchase)

Step1: Calculate cost of jeans before discount

Each pair of jeans is $22.25, 2 pairs: $22.25 × 2 = $44.50

Step2: Apply 20% discount on jeans

20% off means she pays 80% (1 - 0.20 = 0.80). So, $44.50 × 0.80 = $35.60

Step3: Calculate cost of shirts

Each shirt is $12.50, 2 shirts: $12.50 × 2 = $25.00

Step4: Total before coupon discount

Add jeans (after discount) and shirts: $35.60 + $25.00 = $60.60

Step5: Apply 25% coupon discount

25% off means she pays 75% (1 - 0.25 = 0.75). So, $60.60 × 0.75 = $45.45

Step1: Calculate 20% of $21.18

20% as a decimal is 0.20. So, $21.18 × 0.20 = $4.236

Step2: Round to nearest dollar

$4.236 rounded to the nearest dollar is $4 (since 0.236 < 0.5, we round down)

Answer:

$45.45
