We know that, Amount in Compound interest is given by :
Given : Principal = $2000
Given : Annual yield is 5% and the interest is compounded quarterly
It means : Interest is compounded 4 times in a year
Substituting all the values in the formula, we get :
X + y = 12
x - y = 4
-----------------add
2x = 16
x = 8
x - y = 4
8 - y = 4
y = 4
answer
two numbers: 8 and 4
doule check
sum = 8 + 4 = 12
difference = 8 - 4 = 4
The answer is 7 hope that helped and have a good and always good luck
