Bill excluding service charge is (12.5+28.55+8.95)$=50$
As service charge is 15% of the bill,its value is
15% of 50$,that is 7.5$
So the bill is (50$+7.5$)=57.5$

Bill is $57.50

Total without service charge = $21.50 + $28.55 + $8.95 = $50

Service charge 15% = $50 *15/100 = $7.50

Total bill = Service charge + main charge
Total bill = $7.50 + $50 = $57.50

let the total bill be x
12.50 + 28.55 + 8.95 + 15% of x = x
50.00 + 3x/20 = x
50.00 = x - 3x/20
50.00 = 17x/20
x = 58.82

(12.5+28.55+8.95)$=50$
As service charge is 15% of the bill,its value is
15% of 50$,that is 7.5$
So the bill including service charhge will be (50$+7.5$)=57.50 $ (Ans)

for starter = $12.50
for main courses = $28.55
for deserts = $8.95
service charges = 15%

First add all amount of bill

12.50+28.55+8.95=50
now apply service charges = 15x50÷100 = 7.5

Add service charges in the bill = 50+7.5 =57.5

The total bill included service charges is $57.5
