a photographer charges a sitting fee of $15, and charges $4 for each 5-in. by 7-in.photograph the customer order. the linear function c=15+4n can be used to calculate the customer's cost (c) based on the number of photographs (n) purchased. How many photographs can be purchased if you cannot spend more than $50.00?

Answer:

C. 8

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

n

=

35

4

Decimal Form:

The number of photographs that can be purchased is 8.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

Given the linear function

c = 15 + 4n where n is the number of photographs purchased and c is the cost

Also given that we cannot spend more than $50.00

So,

c ≤ 50

⇒ 15 + 4n ≤ 50

⇒ 4n ≤ 35

⇒ n ≤ 8.75

So, it will be 8 photographs logically because there is no sense of 0.75 photographs since it is a whole quantity.

Hence "The number of photographs that can be purchased is 8".
