In October, Greg and Thomas had the same amount of money in their savings accounts. In November, Greg deposited $120 into his account. Thomas increased the money in his account by 20%. When they compared their balances, they found that they were still equal. How much money did each person have in his account in October?
Let's give the variable that you are trying to answer for a symbol. Let's call it X.
X = the amount of money both Greg and Thomas had in October
We know that in November, Greg added $120 to his account. So, Greg's account has: X + 120
We know that Thomas increased the money in his account by 20%, so Thomas' account has: X + 0.2X, or 1.2X
We know that these two amounts are equal:
X + 120 = 1.2X
Solve for X:
X + 120 - X = 1.2X - X
120 = .2X
120 / .2 = .2X / .2
600 = X
Answer:
The answer is 600 for people who don't understand the other answer ( not to be rude, It is a really good answer )
