Question

To mail a letter to Vienna, Austria the post office charges a flat rate of $9.75 and an additional $0.50 for every ounce the letter weighs. The cost of mailing a letter is determined by the equation y=0.50x+9.75, where y is the cost of the postage and x is the weight of the letter in ounces.

Answer 1

Missing details

Which type of function model would be appropriate for this situation?

Answer:

Linear function

Explanation:

Given

`y = 0.50x +9.75`

Required

The function model

A function of the form:

`y = mx + b`

is referred to as a linear function where

`m = slope/rate`

`b=y\ intercept`

By comparison:

`m = 0.50\ b = 9.75`

So, it is a linear function (linear model)
