write an expression in simplest form that represents the income from w women and m men getting a hair cut and shampoo.

Question

Women: $45 in hair cuts, $12 in shampoos. Men: $15 in hair cuts and $7 in shampoos.

Answer 1

Michael,

 

Let m = number of men.

Let w = number of women.

 

The statement says that women and men get both a haircut and shampoo.

 

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

 

Or

 

m($15 + $7) + w($45 + $12)

 

Which leads to:

 

22m + 57w

 

Hope this helps!
