21000 x 1.05= A
A x 1.05= B

Take $21,000 and multiply by .05. Add the answer to the $21,000.00 to get your first year salary raise.
The questions states that she will receive a 5% at the end of each year so take the total of the first year and multiply by .05 to get the second year salary. Then do the same for the 3rd year. Percentages are very easy.

Okay, right now Julia's getting 21,000 and it's year 0.
At the end of year one, she will get the 21,000 and 5% more. How to figure the percent? Easier than you think:
What is 10%?
(Move the decimal over once= 21,000.0= 2100.00)
Take half of that=
1050
Add that to 21,000.
You now have year one! = 22,050
Now do the same for the next two years. (For year two, take 5 percent of 22,050 and add it to it. And the same for year three!)

5% of $21,000 =$1050. Add that to the original $21,000 and you get $22,050. That is for the first year. Now do 5% of the new answer and add that to the $22,500, and that is the answer for the second year. Repeat for the third year.

If you want to answer it through formula, it could be stated with:
Julia earning in three years = 21000 (1+0.5)^3 =24310.125
But it would be better if you could understand what is happened behind the formula.
In the first year Julia salary increase 5 %, so it become 100+5 =105 % from the original value. or
105/100 *2100 = 1.05 *21000
after the end of second year it would be increase 5 % again from the first year value = 1.05 *(first year) =
1.05* (1.05*21000)
after the third year 1.05 * (second year) = 1.05*(1.05*1.05*21000) = (1.05)^3*21000= 24310.125

Year 1 - 21000.00 x 5% = 1050.00 + 21000.00 = 22500.00
Year 2 - 22500.00 x 5% = 1125.00 + 22500.00 = 23625.00
Year 3 - 23625.00 x 5% = 1181.25 + 23625.00 = 24806.25

$21,000 x .05(5%) = $1,050
Year One Salary: $22,050
$22,050 x 0.05= $1,102.5
Year Two Salary: $23,152.5
$23,152.5 x .05 = $1157.625
Year Three Salary: $24,310.125
Sorry I messed up the first time
