The equation 23 plus 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 ​$79 to deliver.

Question

The appliance weighs enter your ____ pounds.

Answer 1

The equation is 23 + 0.35p = c, where c represents the cost in dollars and p represents the weight in pounds. We are given that c = $79.

Substituting $79 for c in the equation, we have:

23 + 0.35p = 79

Subtracting 23 from both sides:

0.35p = 56

Dividing both sides by 0.35:

p = 160

Therefore, the weight of the appliance that costs $79 to deliver is 160 pounds.
