Diana and sue clean homes for a summer job. the charge 70$ per house plus 15%tip. if they clean 3 house per week how much tip do, they make per week?

Diana and sue made $ 241.5 per week

Solution:

Given that Diana and Sue clean homes for a summer job

The charge 70$ per house plus 15% tip

charge = $ 70 plus 15 % tip

So 15 % tip is made for $ 70

charge per house is given as:

charge per house = 70 + 15 % of 70

Thus charge per house is $ 80.5

If they clean 3 house per week, then the total charge is:

charge for 3 house = charge for 1 house x 3

Thus Diana and sue made $ 241.5 per week
