Camille is attending a fundraiser. She pays for her admission and buys raffle tickets for
$
5
$5dollar sign, 5 each. If she buys
10
1010 raffle tickets, then she would spend a total of
$
135
$135dollar sign, 135 at the fundraiser.
The number
S
SS of dollars Camille spends at the fundraiser is a function of
r
rr, the number of raffle tickets she buys.
Write the function's formula.

answer: 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.

r(0,90)(x,y) . t(-5,0)
