A group of 10 friends had lunch together at a restaurant. The meal cost a total of $99.50, including a 15% tip. How much was the total bill for lunch before the tip?

Answer 1

each meal was $9.95 a peice aND EACH HAD TO pay $1.50 on the tip

Answer 2

Cost of meal before tip + 15% = $99.50

Adding 15% is equal to multiplying by 1.15

Cost of meal before tip x 1.15 = 99.5

This can be rearranged to give;

Cost of meal before tip =
`(99.5)/(1.15)`

Cost of meal before tip = $86.52
