Franklin deposited $75 in a no-interest bank account when he opened it. After that, he deposits $50 per month in the account. Assume he makes no other withdrawals or deposits. The equation can be used to find m, the number of months it will take him to save a total of $175. 75 plus ? m is equal to 175 What number should he use as the coefficient of m ?
Franklin starts with $75 and adds $50 for each month, so the total after m months is 75 + 50m. In the equation 75 + ?m = 175, the coefficient of m is 50, the monthly deposit. The correct choice is C, 50.
