Question

A group of 3 friends order a combo meal which includes two slices of pizza and a drink. Each drink is priced at $2.50. If the combined total is $31.50, how much is the cost of a slice of pizza

Answer 1

The cost of each slice of pizza is $ 14.5

Explanation:

Given as :

The combined total of 2 slices and 1 drink cost = $ 31.50

The price of each drink = $ 2.50

Let The number of slices = S

The number of drink = D

According to question

2 × S + 1 × D = $ 31.50

∵ 1 drink cost $ 2.50

So, 2 × S + 1 × D = $ 31.50

Or, 2 × S + 1 × $ 2.50 = $ 31.50

Or, 2 × S = $ 31.50 - $ 2.50

Or , 2 × S = $ 29

∴ S =
`(29)/(2)` = $ 14.5

Hence The cost of each slice of pizza is $ 14.5 Answer
