Question

Anyone know the answer to number 75? I have more questions coming!

Answer 1

Convert 15% to a decimal. When converting percents to decimals, move decimal 2 digits to the left: .15

Find 15% of 1000 gallons: .15 x 1000 gallons = 150 gallons

So the new machine uses 150 gallons less:
Old Machine gallons - 15% of Old Machine gallons = New machine gallons
1000 gallons -150 gallons = 850 gallons

Answer 2

D) bc 15% of 1000 is 150 and 1000-150 is 850.
