Ken has $950 in a savings account at the beginning of the summer. he wants to have at least $600 in the account by the end of the summer. he withdraws $35 a week for food, clothes and movie tickets. write an inequality for the number of weeks ken can withdraw money, and describe the solution.

Every week he withdraws $35 from the $950 in his savings, and he wants at least $600 by the end of the summer. So we could write:



Where 'x' is the number of weeks. Now let's solve it for 'x'.

Subtract 950 to both sides:



Divide -35 to both sides, don't forget to switch the sign when dividing/multiplying by a negative number:



So he can only withdraw at money for at most 10 weeks if he wants at least $600 left in his account.
