ANSWER
a) 65m + 675 = 2300
b) 25 months
Step-by-step explanation
a) Bill has $675 in his savings account. He is going to put $65 each month.
Let the number of months it will take him to get to $2300 be m.
After m months, Bill will have added:
$65 * m = $65m
We want to find the equation that can help us find the number of months.
Since he already has $675 in the account and he is adding $65 every month, we have that:
2300 = 675 + 65m
(Option D)
b) To find m, we simplify by collecting like terms:
65m + 675 = 2300
65m = 2300 - 675
65m = 1625
Divide through by 65:
m = 675 / 65
m = 25 months
Therefore, it will take 25 months for Bill to have $2,300 in his savings account.
