Answer:
The answer is 600 for people who don't understand the other answer ( not to be rude, It is a really good answer )
Step-by-step explanation:
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
