Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation . From there we can solve for x.
Firstly, multiply both sides by 5:
Next, divide both sides by 4 and your answer will be

Answer:
The cost of tuition fee after 4 years is $15,149.72.
Step-by-step explanation:
Exponential function:
A= the amount after n years
P= Initial amount
r= rate of increasing
n= time in years
The cost of tuition at a college is $12,000. It is increasing at the rate of 6% each year.
Here, P= $12,000, r= 6%= 0.06, n= 4 years.
=$15,149.72
The cost of tuition fee after 4 years is $15,149.72.
