Question

Mr. Simpson is buying jerseys for his High School football team. Thejerseys cost $0 each and there is a processing fee of $65 to process Mr.Simpson's purchase,Write a linear equation representing Mr. Simpson's total cost for buying xnumber of jerseysWhat is Mr. Simpson's total cost, if he purchases 40 football jerseys?

Answer 1

The linear equation is: y = 80x + 65

Te cost for 40 football jerseys: $3265

Step-by-step explanation

Let 'x' be the number of jerseys and 'y' the cost of x jerseys.

Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.

Therefore, the cost 'y' of x jerseys is:

`y=80x+65`

Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:

`\begin{gathered} y=80\cdot40+65 \\ y=3200+65 \\ y=3265 \end{gathered}`
