Answer:

Bill: 8 years

Hoang: 13 years

Step-by-step explanation:

Let's say Hoang has been a nurse for H years and Bill has been a nurse for B years.

Hoang has been a nurse for 5 years longer than Bill. This means that B + 5 = H

Next, 3 years ago, she had been there twice as long.

(B-3) and (H-3) represent Bill and Hoang 3 years ago respectively.

(B-3) * 2 = (H-3)

We thus have two equations

B+5 = H

(B-3) * 2 = H-3

Substitute B+5 for H in the second equation

2*B - 6 = B+5-3

2B-6 = B+2

add 6 to both sides to put all the constants on one side

2B = B + 8

subtract B from both sides to isolate the variable

B = 8

H = B+5 = 13

An easy way to solve fraction problems like this is to make each fraction have the same denominator.  Since he has $100, the denominator will be 100.
2/10=?/100    10*10=100  1*10=20   20/100 of his money he wants to spend on video games
55/100 already has 100 as its denominator, so he wants to spend 55/100 on a skateboard.
3/10=?/100   10*10=100   3*10=100  30/100 is how much he wants to spend on comic books.
Add all of the fractions together to see how much he wants to spend and if he has enough.
20/100+55/100+30/100=105/100
He wants to spend $105, which is $5 more than he has.
