Answer 1

Expression for income
`57w+22m`

Explanation:

Given

Let w is income of women and m is income of men

Woman haircut = $45

Men haircut = $15

Women shampoo = $12

Men shampoo = $7

The income from men and women getting a haircut and a shampoo is

Income = number of women*(haircut price and shampoo price) + number of men*(haircut price and shampoo price)

`income = m($45 + $12) + w($15 + $7)`

`income = w($57) + m($22)`

The expression in simplest form that represents the income

`57w+22m`
