Answer:
write in y slope intercept form
Explanation:
The price of each raffle ticket is constant, so we're dealing with a linear relationship.
We could write the desired formula in slope-intercept form: S= bS=mr+bS, equals, . In this form, m gives us the slope of the graph of the function and gives us the y-intercept. Our goal is to find the values of bbstart and substitute them into this formula.
We know that the amount of money Camille spends increases b $5 for each raffle ticket she buys, so the slope m, and our function looks like bS=5r+bS, equals,
We also know that if Camille buys 10 raffle tickets, then she would spend a total of $ 135 at the fundraiser, which means that when r=10r equals, 10, S=135S=135S, equals, 135. We can substitute this into the formula of the function to find
5⋅10+b
50+b
b
=135
=135
=85
This means admission to the fundraiser costs $85 equals,b=85 equals, 85, end , the desired formula is: S=5r+85
