Jane is organizing a fundraiser to buy a ping-pong table for the community center. the table costs $500.00. jane is asking contributors to pay for an equal share of the cost of the table. she already has five contributors lined up. what function models the cost per share, c, with respect to the number of new contributors, n? how many new contributors must jane recruit in order for the cost of each share to be $20.00?

Function: C = 500 / n

Jane must recruit 20 more contributors or 25 contributors in total for the cost of each share to be $20.

Step-by-step explanation:

1. Cost per share, C, with respect to the number of contributors, n is

C = 500 / n

So, with 5 contributors, the price is $100 per share. $100 = 500/5

2. C= $20

20= 500 / n

20 * n = 500 * n

20n = 500

n= 25

She already has 5 contributors, so she needs 20 more.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
