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.
website 1:

website 2:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

combine all like terms then its just a 2 step equation
