Algebra 1 the appliance weighs how many pounds?

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 ​$72 to deliver.

how many pounds does the appliance weigh



Answer 1

30 + 0.35p = c

we are told that c = 72

substitute 72 for c in the above equation to solve for p

30 + 0.35p = 72

30 - 30 + 0.35p = 72 - 30

0.35p = 42

0.35p/0.35 = 42/0.35

p = 120
