Answer:

Here, x represents the amount of time that the money is accruing interest.
Step-by-step explanation:
The function below represents the annual interest Alexander earns on a savings account.
f(x) = 500(1 +0.02)x
Here, x represents the amount of time that the money is accruing interest.
We know that, if R% of interest is accrued over a principal of P over time , T,
then the net interest accrued is given by,
P×R×T/100
4/5 of x -3/4 of x =5
solution by LCM
16x-15x/20 =5
x/20 =5
x=100

Answer:
7 days
Step-by-step explanation:
Five men do 200 yards in one day
One man does 200/5 = 40 yards in 1 day.

8 men can do 40 * 8 = 320 yards in 1 day
=============
2240 yards / 320 yards = 7 days
