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.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
