The equation 29 + 0.25p = 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 $64 to deliver.
To find the weight of an appliance that costs $64 to deliver, we can substitute the value of c as $64 into the equation and solve for p.
29 + 0.25p = 64
Subtracting 29 from both sides:
0.25p = 35
Dividing both sides by 0.25:
p = 140
Therefore, the weight of the appliance that costs $64 to deliver is 140 pounds.
To find the weight of an appliance that costs $64 to deliver using the equation 29 + 0.25p = c, we can set c = 64 and solve for p.
Substituting c = 64 into the equation, we have:
29 + 0.25p = 64
To isolate p, we subtract 29 from both sides:
0.25p = 64 - 29
0.25p = 35
Dividing both sides by 0.25:
p = 35 / 0.25
p = 140
Therefore, the weight of an appliance that costs $64 to deliver is 140 pounds.
