A store offers packing and mailing services to customers. This table is given to customers to help them estimate the cost of shipping a box based on its weight in pounds, and a flat rate of $5 for packing. Which equation represents the shipping cost as a function of x, the weight in pounds? a. f(x) = 2.25x + 5. b. f(x) = 3.5x + 4. c. f(x) = 4x + 9. d. f(x) = 9x + 14

Respuesta :

Answer:

f(x) = 2.25x + 5

Step-by-step explanation:

As given, the cost of shipping a box is based on its weight in pounds, and a flat rate of $5 for packing. This means $5 is common for each parcel that will be sent. Only the weight will vary.

So, option first f(x)=2.25x+5 is the correct answer. Here 2.25 is the per pound rate. Like if someone wants to send a parcel weighing 3 pounds, the price will be :

f(x)=2.25*3 +5

= $11.75

The function that shows the shi[ping cost as a function of x is f(x) = 2.25x + 5.

How is the function related to the shipping cost?

The function tells us that there is a constant 5. This constant is the flat rate of 5 dollars which is the rate for packing.

X is a variable whose values can change based on the weight of the package that is to be sent.
