Hayden had 21/2 gallons of water in his watering can. The seed packet said to use 14 of a gallon for peppers and 58 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 34 gallons of water left over, about how much water did he use for lettuce?

the answer is idk lol you thought i knew the answer PLS

It would help if you proofread your questions before you posted them.

Are you missing some decimal points (.)? Also 21/2 (= 10.5) is not the same as 2 1/2.

just another who will not type fractions clearly.
