The track team plans to buy new jerseys. If they buy more than 25 jerseys, the cost is $12.99 each. The total cost of the jerseys is a function of the number purchased, n. C(n) = 12.99n Use the drop-down menus to complete the statements below about the domain of this function.

The answer is below

Step-by-step explanation:

A function shows the relationship between two variables (that is an independent variable and a dependent variable).

The domain of a function is the set of all input variables (that is independent variables).

Given the function C(n) = 12.99n, C(n) is the dependent variable representing the cost and n is the dependent variable which is the number of jerseys.

Since the customer has to buy more than 25 jerseys, the domain is:

Domain = 25 < n ≤ ∝

correct answer is b. 27/8

step-by-step explanation:

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b
