Keith has $500 in a savings account at the beginning of the summer. He wants to have at least $200 at the end of the summer. He withdraws $25 per week for food. How many weeks can Keith withdraw money from his account?

Respuesta :

Keith can withdraw money from his account for 12 weeks.

Step-by-step explanation:

Total savings = $500

Amount to be left in his account = $200

Withdrawal per week = $25

Let,

x be the number of weeks.

According to given statement;

Total savings - Withdrawal per week * no. of weeks = Amount to be left

[tex]500-25x=200\\-25x=200-500\\-25x=-300\\[/tex]

Dividing both sides by -25

[tex]\frac{-25x}{-25}=\frac{-300}{-25}\\x=12[/tex]

Keith can withdraw money from his account for 12 weeks.
