Jesse has 2 coupons, but can only use one of them. coupon a is for $10 dollars off an item. coupon b is for 25% off an item. the product he is buying costs $42. which coupon is the better deal?

coupon b offers $10.50 off whereas the other is only for $10 off

Step-by-step explanation:

25%*42=10.5

Step 3

Step-by-step explanation:

The mistake was made in Step 3.

Step 1: Subtract the wholes. 4 - 1 = 3

Step 2: Subtract the fractions. 5/6 - 3/6 = 2/6

After Step 2, He should have added them instead of subtracting them:

3 + 2/6 = 3 2/6

So, step 3 was his mistake.
