Lukas Wise · Answer 2

Answer: - 14 gallons.

Step-by-step explanation:

Given : Seven days ago, the gas tank on Roses car was filled with 20 gallons of gasoline.

Today there are 6 gallons of gasoline.

∵ 20> 6, it means there is decrease in the amount gasoline.

Change of gasoline in the past seven days = Amount gasoline seven days before - Amount gasoline now.

i. e. Change of gasoline in the past seven days = 20 gallon - 6 gallons=14 gallons

Since decrease is represented by negative (-) sign in integers.

∴ The integer represents the change of gasoline in the past seven days = - 14 gallons.
