Explanation:

Step 1: Determine the sales tax

Taxable income=granola cost+apple cost+vitamin water cost

where;

granola cost=2×1.59=3.18

apple=1×0.89=0.89

vitamin water=2×1.39=2.78

replacing;

Taxable income=3.18+0.89+2.78=$6.85

Sales tax=7.5%×6.85=$0.51375

Step 2: Determine the total amount he paid

Total amount he paid=cost of gas+taxable income+sales tax

where;

cost of gas=12×2.89=$34.68

taxable income=$6.85

Sales tax=$0.51375

replacing;

Total amount he should have paid=34.68+6.85+0.51375=$42.04375=$42.04

Step 3: Determine discount

Discount=44.64-42.04=$2.60

If Leon paid $44.64, then he had a $2.60 discount for his purchase
