To check how much water Noah needed for 7 plants at 14 ounces each using an addition equation, he can add the amount of water needed for each plant together. Since he has 7 plants each needing 14 ounces of water, the correct addition equation would be:
14 + 14 + 14 + 14 + 14 + 14 + 14 = 98
So, the correct response is:
14 + 14 + 14 + 14 + 14 + 14 + 14 = 98
