Deanna has $150.00 in her account. At the end of each week, she plans to take $15.00 out of her account for her spending money. Write an equation to show the relationship between the number of weeks and the balance in the account

Let the balance = Y and the number of weeks = x

She takes out 15 per week, so multiply 15 by x (the number of weeks) to get 15x.

You would then want to subtract that from the amount she started with in her account.

The equation becomes: Y = 150 - 15x
