Calculate the total cost of the order: veggiburger with cola and soup, sales tax 4%, tip 15. veggiburger: $3.25 cola: $1.50 soup: $2.25 a $8.33 b $7.28 c $7.00 d $5.50

Add the prices of the food together to get $7. Then you calculate the sales tax, which is 1.04 * $7 = $7.28. The tip is 15% I am assuming, and not 15, so it would be $7 * 0.15 = $1.05. Add $1.05 with $7.28 to get $8.33, so the answer is A.
