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
