Answer 1

Answer:

Caleb paid less than Omar by $12.

Step-by-step 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: $920-(0.15\times920)=782$ 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: $1000-(0.15\times1000)=850$

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.
