Respuesta :

Answer:

It will take will 7 weeks to afford a car.

Step-by-step explanation:

  • First, work out how many hours a week he works:

        7 hours a day x 6 days a week = 42 hours a week.

  • Then, calculate his weekly wage:

        42 hours a week x £9.20 = £386.40 / week

  • To find how much of his wages he keeps, turn the ratio into a fraction. To do this, add all parts of the ratio to get the denominator, and then the part of the ratio you want to find is the numerator:

        5 + 2 = 7

        simons weekly wage = [tex]\frac{5}{7}[/tex] × 386.40 = £276

  • Finally, to find out how many weeks it will take, divide the amount needed (£1932) by the amount per week (£276)

        This should give you an answer of 7 weeks.
