The function A(b) relates the area of a trapezoid with a given height of 14 and one base length of 5 with the length of its othe
r base. It takes as input the other base value, and returns as output the area of the trapezoid. A(b)=14*(b+5/2) Which equation below represents the inverse function B(a), which takes the trapezoid's area as input and returns as output the length of the other base?

Answer:
The value of first coin will be $151.51 more than second coin in 15 years.
Step-by-step explanation:
You have just purchased two coins at a price of $670 each.
You believe that first coin's value will increase at a rate of 7.1% and second coin's value 6.5% per year.
We have to calculate the first coin's value after 15 years by using the formula
Where A = Future value
P = Present value
r = rate of interest
n = time in years
Now we put the values
A = (670)(2.797964)
A = 1874.635622 ≈ $1874.64
Now we will calculate the value of second coin.
A = 670 × 2.571841
A = $1723.13
The difference of the value after 15 years = 1874.64 - 1723.13 = $151.51
The value of first coin will be $151.51 more than second coin in 15 years.
