Assign variables to the groups. "S" stands for senior citizens and "C" stands for children. 


3S + 9C = 75

8S + 5C = 67

We must cancel one of these variables out; I did this by multiplying the top equation by 8 and the bottom equation by 3.

24S + 72C = 600
24S + 15C = 201

Subtract these two expressions and you get C = 7. Plug 7 in for C into any of the above expressions and solve for S. You will find that S = 4.

Trava [24]

Answer:

She will receive $24,000 after paying taxes

Step-by-step explanation:

This question can be solved using a rule of three.

20% of her money has to go to the state for taxes. So she will receive 100-20 = 80%. $30000 is 100% = 1. How much is 80% = 0.8?

$30000 - 1

$x - 0.8

x = 30000*0.8

x = 24000

She will receive $24,000 after paying taxes
