The equation 23 plus 0.35 pequalsc 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 information provided is incomplete as the equation 23 + 0.35p = c is given but the value of c is missing. Please provide the value of c in order to find the weight of an appliance that costs $79 to deliver.
To find the weight of an appliance that costs $79 to deliver, we can use the given equation: 23 + 0.35p = c, where p represents the weight of the appliance in pounds, and c represents the cost in dollars.
We can create a table to solve this equation:
| p | c |
|-----|-----|
| 0 | 23 |
| 10 | 26 |
| 20 | 29 |
| 30 | 32 |
| 40 | 35 |
| 50 | 38 |
| 60 | 41 |
| 70 | 44 |
| 80 | 47 |
| 90 | 50 |
| 100 | 53 |
By examining the table, we can see that when c is equal to 79, the corresponding value of p is 60 pounds. Therefore, the weight of the appliance that costs $79 to deliver is 60 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.
1. Subtract 23 from both sides of the equation:
23 + 0.35p - 23 = 79 - 23
0.35p = 56
2. Divide both sides of the equation by 0.35:
p = 56 / 0.35
p = 160
Therefore, the weight of the appliance that costs $79 to deliver is 160 pounds.
