Final answer:
The shopper will save 80 cents more by taking the better-valued approach.
Step-by-step explanation:
To find out how much more money the shopper will save by taking the better-valued approach, we need to calculate the final price using both discount approaches and compare them.
- Approach 1: First, apply the $4.00 discount and then the 20% off discount. Start with the original price of $25. Subtract $4.00 to get $21.00. Then, apply the 20% discount by multiplying $21.00 by 0.20, which gives a $4.20 discount. Subtract $4.20 from $21.00 to get the final price of $16.80.
- Approach 2: First, apply the 20% discount and then the $4.00 discount. Start with the original price of $25. Apply the 20% discount by multiplying $25.00 by 0.20, which gives a $5.00 discount. Subtract $5.00 from $25.00 to get $20.00. Then, subtract $4.00 from $20.00 to get the final price of $16.00.
The shopper will save $16.80 - $16.00 = $0.80 more by taking the better-valued approach. To express this in cents, multiply $0.80 by 100, which answers 80 cents.
