Agenerator contains 60 gallons of fuel and uses 2.5 gallons per hour. a more efficient power generator contains 40 gallons of fuel and uses 1.5 gallond per hour. after how many hours do the generators have the same amount of fuel? which generator runs longer? justify your answers

After how many hours do the generators have the same amount of fuel?

60 - 2.5x = 40 - 1.5x --> x = 20 hours

Which generator runs longer?

60/2.5 = 24 hours

40/1.5 = 26 2/3 hours

The more efficient power generator runs 2 2/3 hours longer.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
