the problem is the Spanish Club begins the school year with a $50 balance in its account. To raise money for activities during the school year, the club has bake sales every Friday after school. The table shows the club’s balance after the bake sale. Write an equation to represent the Spanish Club’s account balance after x weeks.

y=18x+50

Step-by-step explanation:

We can use a graph to solve this. Using y=mx+b, we can replace these variables with numbers.

First, we need to find the y-coordinate. This can be solved with 50 because they begin with $50. So we have y=mx+50

Next, we need to find the slope. We can make points by choosing random balances. I'll choose (2,86) and (4,122). We can find the slope through rise/run, and get 36/2, which would be 18. Now we can put this here. y=18x+50

And that is our answer! You can also use f(x) in place of y.

step-by-step explanation:

32.50-7.50=25

225/25=11
