Answer:
47 weeks
Explanation:
First, find how much he makes in a week
Multiply his hourly wage by the hours he works
5*20=100
He make $100 a week
To find how many weeks until he can afford the car, divide the cost of the car by how much he make a week
4650/100=46.5
It will take him 46.5 weeks, but because he doesn't get paid for 1/2 week, he has to work a full 47 weeks
Hope this helps! :)
