Question

A neighborhood group wants to build a new playground using donations from residents. The amount needed from each donor varies inversely to the number of people donating. If 25 people donate, each of them would need to contribute $135. Solve for the amount each person needs to contribute if 45 people donate.

Answer 1

First of all, we need to find out how much money is needed ,

25 x $ 135 = $ 3375 

Next, we just need to divide this amount to total contributors

$ 3375 / 45 = $ 75 per person

Hope this helps
 

Answer 2

Answer:

Each person needs to contribute is $75.

Step by step explanation:

It is given that the number of people is 25. Each of them would need to contribute $135.

Total amount contributed by 25 people is the product of 25 and 135.

$25\times 135=3375$

Total amount contributed by 25 people is $3375.

Now 45 people has to contribute the same amount $3375.

If 45 people donate $3375, then each people donate

$\frac{3375}{45}=75$

Therefore, each person needs to contribute is $75.
