Question

Mrs. Gabriel's monthly salary is Php 18,000 plus a 7% commission on her sales. If she wants to earn at least Php 25,000 a month, what must be the amount of her sales?

Answer 1

18000 of it was her salary.

that leaves 3000 commission.

3000/.12 = 25000.

she made sales of 25000.

the formula for her pay would be pay = 18000 + .12 * sales

if sales is 25000, then formula for pay becomes:

pay = 18000 + .12 * 25000

simplify to get:

pay = 18000 + 3000

combine like terms to get:

pay = 21000
