Question

Justin is considering two websites for downloading music.The costs are detailed here.

Website 1: a yearly fee of $30 and $1.50 for each download

Website 2: $2 for each download

What is a system of equations to represent the costs for one year?

Express your equations in the form of y=mx+b where x is the number of downloads for the year and y is the total cost for the year.

Enter your equations in the boxes.

Answer 1

y = 30 + 1.5x and y = 2x

Explanation:

Website 1 has a plan for a yearly fee of $30 and $1.5 for each download.

Therefore, if x is the number of downloads for a year and y is the total cost for the year, then we can model the conditions as

y = 30 + 1.5x ......... (1)

Website 2 has a plan of $2 for each download.

Therefore, we can models the condition as

y = 2x ........ (2)

Therefore, equations (1) and (2) represent the costs for one year. (Answer)
