Explanation
The items cost $90.35 before the discount: 3 cookbooks cost $56.67, the measuring cups cost $2.68, 4 utensils cost $21.40, and the cooling rack costs $9.60. After the $5 discount, the purchase is $85.35, so standard shipping is $5.25 and the correct total is $90.60. Ross was billed $94.35, which is $3.75 too much; choice C says he was overcharged by $3.75.
