Answer:
- Caleb paid less than Omar by $12.
Explanation:
The initial cost of each repair is $1,000.
One coupon is for $80 off the repair cost. The other coupon is for 15% off the repair cost.
Case 1: Omar uses the $80 off the repair cost coupon first. He then uses the 15% off the repair cost coupon on the remaining balance.
Step 1: 1000 − 80 = 920
Step 2: 920− (0.15 × 920) = 782 dollars
Case 2: Caleb uses the 15% off the repair cost coupon first. He then uses the $80 off the repair cost coupon on the remaining balance.
Step 1: 1000−(0.15 × 1000)=850
Step 2: 850 − 80 = 770 dollars
Now, comparing the values we can see that Caleb paid less.
He paid less by 782 − 770 = 12 dollars.
