Question

20. Lee uses Bill Payer from his bank account to pay his internet bill. Lee pays the same amount each month.

At the end of the year, Lee notices that a total of $600 has been withdrawn from his bank account to pay for the internet bill. Which integer represents the amount by which Lee’s bank account changed each month?
A) -25
B) -50
C) -60
D) -100

Answer 1

it's the same amount each month, for a year. So:
total money ÷ times money was taken out= how much has been taken out.

$600÷12=50
