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?

Respuesta :

The given equation is

[tex]c=2.4p[/tex]

For 1 pound, we solve when p = 1.

[tex]c=2.4\cdot1=2.4[/tex]

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

For p = 6.5, we have.

[tex]c=2.4\cdot6.5=15.6[/tex]

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

If a customer spent $8.40, then

[tex]\begin{gathered} 8.40=2.4p \\ p=\frac{8.40}{2.40} \\ p=3.50 \end{gathered}[/tex]

(c) The customer purchased 3.50 pounds.
