Question

Anne has $210 in a savings account. She withdraws $25 per month. What is the equation that describes the linear relationship?

A) y = 25x - 210
B) y = 25x + 210
C) y = 210x - 25
D) y = 210 - 25x

Answer 1

The correct linear equation that represents Anne's savings account as she withdraws $25 per month is y = 210 - 25x, which matches answer choice D.

Step-by-step explanation:

The equation that describes the linear relationship between the amount of money Anne has in her savings account and the number of months that pass as she withdraws money is y = 210 - 25x. Here, y represents the amount of money remaining in the account after a certain number of months (x). The starting amount, $210, is the y-intercept of the equation, since this is the amount she has when no months have passed (x=0). The slope of the equation is -25, which reflects the rate at which money is withdrawn from the account each month.

Therefore, the correct answer is D) y = 210 - 25x.
