Hi!
1/4 of 20 pencils are 5 pencils.
Since he gave away 4 pencils,
Total = 5 + 4 = 9
Mr. Simms use and give away total 9 pencils.
5-12 ÷(6-2)-1
Do whats in the parenthesis
5-12 ÷4-1
Do division next
5- 3- 1 = 1.
Do the same for the next.
(4-3) x 2+15 ÷(6-1)
1 x 2+15 ÷5
2+15÷5
2+3= 5
15/72=5/24
Divide both by three.

Answer:
The total compound return over the 3 years is 15.26%
Step-by-step explanation:
Let the initial investment sum be assumed to be X
The total return after each year can be calculated as follows:
After First year: X + (13% of X) = 1.13X
After Second year: 1.13X + (20% of 1.13X) = 1.13X + 0.226X = 1.356X
After Third year: 1.356X - (15% of 1.356X) = 1.356X - 0.2034X = 1.1526X
It is apparent from here that after the third year, the investment has increased the initial X, by 0.1526X, which is 15.26%.
The total compound return over the 3 years is 15.26%
The answer is -3 3/12 or -3 1/4
