500 - 13% = 87% of 500 = 500*87/100 = 435
60 decreased by 40 is 20.
20 x 25 = 500
Answer: 45% Work: 20 is decreased to 11 9 = D x 20 --- ---- 20 20 20 divided by 9 = .45 .45 as a percent = 45 %
20milles per gallon
20 x 25 = 500 square miles.
500 miles.
500 mi / 20 mpg = 25 gallons.
320 decreased by -20 = 300
500 - 17% = 415
500 - 13% = 87% of 500 = 500*87/100 = 435
When 25 is decreased by 20% the result 20.
450 decreased 20% results in: 360
8 hours 20 minutes.

Well if typical car hold 10 gallons, then it will do about 300 miles, (average 30 miles/gallon). so 500 miles trip will requires about 20 gallons of gas. NOTE: if your vehicle does 20-30 miles/gallons, it will require more gas. (estimate 30-40 gallons)
60 decreased by 40 is 20.
