Question

3. Trevon started caring for his

cousin's fish. The fish tank had some
fish in it when he got it. He started
adding 2 fish a month for 7 months.
None of the fish have died and he
currently has 20 fish in the tank. How
many fish did he start with?

Answer 1

6

Explanation:

He added 2 fish a month for 7 months, so he added 2 * 7 = 14 fish.

He currently has 20 fish in the tank, so he started with 20 - 14 = 6 fish.

Answer 2

He started with 6 fish in the tank

Explanation:

2 per month x 7 months = 14

20 total - 14 fish added = 6 initial amount
