Answer:
The company must make $450.
If the company must pay $300, then you will take 300, and since they want to make a profit, which means 1500 dollars more once they pay the 300, the you will add that to 300.
300 + 150 = 450
Now to find how many weeks it will take, you will divide 450 by 60:
450/60 = 7.5
It will take 7 1/2 (or round it to 8)weeks to gain $450, which is enough money to pay the bank $300, and make a profit of $150.
