Camille is attending a fundraiser. she pays for her admission and buys raffle ticket for five dollars each. if she buys 10 raffle tickets then she would spend a total of $135 at the fundraiser. the number s of dollars camille spent at the fundraiser is the function of r, the number of raffle tickets she buys. right the functions formula

The required function formula is,

S(R) = 85 + 5 R

Step-by-step explanation:

Given,

The price of each raffle = $ 5,

⇒ The price of 10 raffle = 10 × 5 = $ 50

Since, her total spending at the fundraiser = Her admission fee + price of raffle she buys,

⇒ Her total spending when she buy 10 raffle = Her admission fee + $ 50

According to the question,

Her admission fee + $ 50 = $ 135

⇒ Her admission fee = 135 - 50 = $ 85

Hence, if she buys R raffle then her spending = 85 + 5 R

Here, S represents her total spending,

⇒ S = 85 + 5 R

Or S(R) = 85 + 5 R

Which is the required function formula.

85+5r

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
