Confused on what to do :/

3women sell hats at a craft fair weekly. the money they make at the fair is split into categories. 9% goes to pay taxes. $55 goes to pay rent for the space they sell in. the rest is split between the women. if the group make $706 at the fair, how much does each women get paid once the money is divided

What multiplys to be 1 but adds up to be 4

Solve 13 + w/7= -18 (w/7 is a fraction)
