Answer: quantity of water left over = 0.96 gallons
Explanation:
Given: Total quantity of water = 2.7 gallons
Water used for tomato plants = 0.98 gallons
Water used for peppers = 0.76 gallons
Total water used = 0.98 +0.76 = 1.74 gallons
Then, quantity of water left over = Total quantity of water - Total water used
= 2.7 - 1.74 gallons
= 0.96 gallons
Hence, quantity of water left over = 0.96 gallons
