Luis makes the following purchases at the store:1 gallon of milk at $2.892 loaves of bread at $2.19 each2 pounds of ham at $6.89 per pound1/2 pound of cheese at $8.38 per poundLuis has a coupon for 75 cents off on the purchase of one loaf of bread that is applied before tax, and he pays 4% sales tax. If Luis paid $29.83 , then he _____ for his purchase.

The purchases cost $2.89 + (2 × $2.19) + (2 × $6.89) + (0.5 × $8.38) = $25.24. After the $0.75 coupon, the taxable total is $24.49; adding 4% tax gives $24.49 × 1.04 = $25.47 (rounded to the nearest cent). Since Luis paid $29.83, he paid $29.83 − $25.47 = $4.36 too much, so the correct choice is “paid $4.36 too much.”
