Question

Dontina is ordering uniforms for her employees. The company Dontina is ordering from charges $18 per uniform and a shipping fee of $7.

Based on this information, which function can be used to represent the relationship between the total cost, c, and the number of uniforms Dontina orders, n?


c = 18n + 7

c = 7n + 18

c=18n−7

c=7n−18

Answer 1

c = 18n + 7

Explanation:

Given the following data;

Total cost is represented by c

Number of uniforms ordered is represented by n

Shipping fee = $7

Cost per uniform = $18

The total cost is equal to the amount of money spent on ordering each uniform ($18) plus the shipping costs ($7).

Translating the word expression into an algebraic equation, we have;

c = 18n + 7

For example, if Dontina is ordering 10 uniforms for her employees.

n = 10

Substituting the value of n into the equation, we have;

c = 18(10) + 7

c = 180 + 7

c = $187

Therefore, the total cost incurred by Dontina in ordering 10 uniforms for her employees is $187.
