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.
The appliance weighs enter your ____ pounds.
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.
To find the weight of an appliance that costs $79 to deliver, we need to use the given equation 23 + 0.35p = c and substitute c = $79. So our new equation becomes:
23 + 0.35p = 79
To solve for p, we need to isolate the variable p. We can start by subtracting 23 from both sides of the equation:
0.35p = 79 - 23
0.35p = 56
Next, we divide both sides of the equation by 0.35 to solve for p:
p = 56 / 0.35
Using a calculator, we can find that p = 160 pounds.
Therefore, the weight of an appliance that costs $79 to deliver is 160 pounds.
To find the weight of an appliance that costs $79 to deliver, we need to solve the equation 23 + 0.35p = 79 for p.
Let's substitute c = 79 into the equation: 23 + 0.35p = 79.
Now, we can solve for p.
Step 1: Subtract 23 from both sides of the equation: 0.35p = 79 - 23.
Simplifying, we get: 0.35p = 56.
Step 2: Divide both sides of the equation by 0.35 to isolate p: p = 56 / 0.35.
Calculating, we find: p ≈ 160 pounds.
Therefore, the weight of the appliance that costs $79 to deliver is approximately 160 pounds.
