Answer:
There are 4 boys for every 6 girls (4 : 6 ratio)
So first, here, subtract 17 from both sides.
17 + 3f = 14
- 17 -17
3f = -3
Then divide both sides by 3
f = -1
It would be 7.45 since the -3.05 and the -9.5 together would equal -12.55 which subtracted from 20 would equal 7.45
7,500 plus the commision is 525 now you add it to the 7,500 that will leave you with 8,025 now you subtract it from 185,000 so the answer will be 176,975
I'm glad if it helps :)
