A high school is doing a fundraiser selling magazine subscriptions. The magazine publisher will pay the school a starting bonus of $500 and they $4 for each magazine subscription sold. At the end of the fundraiser the school is paid $1300. How many subscriptions did they sell?

200

Step-by-step explanation:

You can use the equation 1300=4x+500

Starting bonus ($500) is like the y intercept so you would get that out of the way by subtracting 500 from both side

1300-500=800

500-500=0

Your equation is now:

800=4x

Now since the question is How many subscriptions did they sell and we know that each magazine is $4 all for have to do is divide both sides by 4 to get the answer.

800÷4=200

4x÷4=x

x=200
