15 = ½ (7x-6)
distribute ½ into parentheses
15 = ½(7x) - ½(6)
15 = ⁷/₂x - 3
multiply by 2
30 = 7x -6
subtract +6 to both side
30 + 6 = 7x
36 = 7x
devide 7 to both side
36
------ = x

Answer: the total amount is $18
Step-by-step explanation:
The cost of the meal the Allam ordered was $15. It is customary to leave a tip of 15% for the server. If the tip amount is calculated on the price of the meal before the
tax is applied, then the amount of tip that he gave would be
15/100 × 15 = $2.25
The sales tax in Wisconsin is 5%. The amount of sales tax that he would pay is
5/100 × 15 = $0.75
Therefore, the total amount he would have to pay is
15 + 2.25 + 0.75 = $18
