First you have make the 2 and a half into 5/2. Then you have to find a common denominator of the two fractions, which would be 8. So the 7/8 you dont need to do anything to but the 5/2 you do... so multiply both the top and the bottom by 4 so you can get 8 on the bottom. that would be 20/8. now you can add them. so 7/8 + 20/8 = 27/8
The correct option will be: d. 0.4%
For finding the periodic interest rate , we need to divide the annual interest rate by the number of times interest calculated in a year.
Here, the simple interest is calculated monthly, that means the number of times interest calculated in a year will be 12.
Annual interest rate is 4.8%
So, the periodic interest rate =
%
y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
