Question

Carl is the CEO Non-profit organization called “Carl Cares for Cats”. This organization is quite well off and has a significant amount of money in the bank account. To make matters even better, his organization just received a donation of $13,000 from Patricia Pierson. Carl decides to split the total amount of money that “Carl Cares for Cats” has equally between 3 departments in the organization: The Food department, The Shelter department and The Medical department. If each department ended up with $25,000, how much money did “Carl Cares for Cats” have in the bank account originally?

Answer 1

We know that the total money is 25000 times 3 because they gave 25000 to each department and there are 3 departments.

Money = 25000 x 3

We also know Carl started off with y amount of dollars (placing y, a variable, to represent the unknown amount)

Then he was given 13000 more.

Money = 13000 - y

So, 25000 x 3 = 13000 - y

Now solve for y by subtracting 13000 from both sides of the equation to isolate the variable, y, which represents the answer we are solving for.
