Question

A farmer is selling apples from his orchard. He uses the equation c=2.4p to calculate the total cost, c, for every pound of apples, p. a.) How much does the customer pay for 1 pound of apples? b.) How much would 6.5 pounds of apples cost? c.) A customer spent $8.40. How many pounds of apples did they purchase?

Answer 1

The given equation is

`c=2.4p`

For 1 pound, we solve when p = 1.

`c=2.4\cdot1=2.4`

(a) The cost of 1 pound is $2.40.

For p = 6.5, we have.

`c=2.4\cdot6.5=15.6`

(b) The cost of 6.5 pounds is $15.60.

If a customer spent $8.40, then

`\begin{gathered} 8.40=2.4p \\ p=(8.40)/(2.40) \\ p=3.50 \end{gathered}`

(c) The customer purchased 3.50 pounds.
