Tim and tom are trying to earn money to buy a new game system over a 3-month period. tim saved $45.70 each month. if they need a total of $214.02 to buy the game system, how much does tom need to earn each of the 3 months in order to buy the game system?

25.64
Because if Tim earns 45.70 each month multiply that by 3 which will give you 137.10 take 214.02 subtract 137.10 and you get 76.92 which is the total amount of money that Tom needs to give divide it by 3 and you get 25.64 which gives you the amount he needs to make in a 3 month period

That they are numbers and related to each other.
