To find the weight of an appliance that costs $71 to deliver, we can substitute c = 71 into the equation and solve for p.
22 + 0.35p = 71
Subtract 22 from both sides:
0.35p = 71 - 22
0.35p = 49
To isolate p, divide both sides by 0.35:
p = 49 / 0.35
p ≈ 140
Therefore, the weight of the appliance that costs $71 to deliver is approximately 140 pounds.
The equation 22 + 0.35p = 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 $71 to deliver.
