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.
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.
To find the weight of the appliance that costs $71 to deliver, we can substitute the given values into the equation and solve for p.
Given:
c = $71
The equation is:
22 + 0.35p = c
Substituting the given value:
22 + 0.35p = $71
Now, we can solve for p:
Subtract 22 from both sides:
0.35p = $71 - $22
0.35p = $49
To find the value of p, we divide both sides by 0.35:
p = $49 / 0.35
Calculating the division:
p = 140
Therefore, the weight of an appliance that costs $71 to deliver is 140 pounds.
To find the weight of an appliance that costs $71 to deliver, we can use the given equation:
22 + 0.35p = c
We will substitute c with $71:
22 + 0.35p = 71
Now, we need to solve this equation for the variable p, which represents the weight of the appliance in pounds.
Let's rearrange the equation to isolate p:
0.35p = 71 - 22
0.35p = 49
To determine the value of p, we divide both sides of the equation by 0.35:
p = 49 / 0.35
Using a calculator, we can evaluate this expression to get the weight of the appliance in pounds. Performing the calculation, we find:
p ≈ 140 pounds
Therefore, an appliance that costs $71 to deliver weighs approximately 140 pounds.
