Hayden had 212 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?
212 - 14 - 58 - lettuce = 34 solve for lettuce
But I think some of those numbers in your question might be fractions?
