Keith has $500 in a savings account at the bank at the begging of the summer. he wants to have at least $200 in the account by the end of summer. he withdraws $25 each week for food, clothes, and movie tickets. how many weeks can keith withdraw money from his account?

12 weeks

Step-by-step explanation:

If Keith wants tgo have at least 200 in his account at the end of summer you need to minus it from the original 500 to make a new total.  

Now you will have $300 to work with.  

Since Keith needs $25 a week you will divide your new total ($300) by 25 and it will give you the number of weeks he can sustain this budget.

300/25=12

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
