Answer:
8 weeks
Step-by-step explanation:
So first you find out how much money he makes per week, by doing 7.5 x 20 you will find that. Now you need to find how many weeks it will take, find this by dividing 1200 by the amount he makes per week and you will end up with 8.
8 Weeks
Earning per hour = $7.50
and Javier works 20 hours per week
Therefore, in one week, Javier will earn $7.50 X 20 = $150
To save $1,200.00 for school, Javier will need to work;
1200.00 / amount earned per week
This will give;
1200.00 / 150
= 8 weeks
