A store offers packing and mailing services to customers. The cost of shipping a box is a combination of a flat packing fee of $5 and an amount based on the weight in pounds of the box, $2.25 per pound. Which equation represents the shipping cost as a function of x, the weight in pounds?

f(x) = 2.25x + 5
f(x) = 5x + 2.25
f(x) = 2.25x − 5
f(x) = 5x − 2.25

f(x)=2.25x+5 represents the shipping cost as a function of x, the weight in pounds.

Step-by-step explanation:

Packing fee = $5

Per pound cost = $2.25

Let,

x be the number of pounds, therefore,

x pounds = x*cost per pound

x pounds = x*2.25 = 2.25x

The shipping cost as a function of x will be

f(x)=2.25x+5

f(x)=2.25x+5 represents the shipping cost as a function of x, the weight in pounds.
