Astore 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

Step-by-step explanation:

Given : 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.

i.e. Shipping cost= $5 (Packing fee) + $2.25 × Weight of box.

Let x be the weight of the box in pounds, we get

Shipping cost= $5+$2.25 x

So the equation represents the shipping cost as a function of x, the weight in pounds will be :-
