The equation 18+0.15p=c gives the cost c in dollars that a store charges to deliver an appliance that weighs p pounds. Use the equation and a table to find the weight of an appliance that costs $36 to deliver. The appliance weighs pounds.

1 answer

To find the weight of an appliance that costs $36 to deliver, we can substitute $36 for c in the equation:

18+0.15p=36

Subtract 18 from both sides of the equation:

0.15p=18

Divide both sides by 0.15:

p=120

Therefore, the appliance weighs 120 pounds.
