Question

The equation 30 + 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 $65 to deliver

Answer 1

Given the equation below

$30+0.35p=c$

Where "c" in dollars is the cost that a store charges to deliver an appliance, and "p" is the weight of the appliance.

To find the weight, we would substitute the value of the cost ($65) into the given linear equation.

$\begin{gathered} 30+0.35p=65 \\ 0.35p=65-30 \\ 0.35p=35 \\ p=\frac{35}{0.35} \\ p=100\text{ pounds} \end{gathered}$

The weight of the appliance is

Answer: 100 pounds
