Question

Write the following sentence into an expression using x as your variable: Mario purchases pizza at $7 each, and the cost will be split between he and his brother.

Answer 1

Cost =
`(7x)/(2)`

Explanation:

Let the number of pizza purchased by Mario = x

Cost of one pizza = $7

Total cost of x pizza = Number of pizza × Cost of one pizza

If the cost of will be split between Mario and his brother, expression representing the cost by them individually,

Cost =
`(7x)/(2)`

Therefore, Cost = $
`(7x)/(2)` will be the answer.
