Nice of you to offer 50 points
the constant of proportinality is the sloep or

x is independent variable and y is dependent variable
the independent variable influences the value of the dependent variable
in this case, the number of months influences the amount of money saved
to find the slope, you do
x=number of months
y=amount
we have
4months, $50
8 months, $100
18 months, $225
or
(x,y)
(4,50)
(8,100)
(18,225)
we can compare
the slope between the points (a,b) and (c,d) is
(d-b)/(c-a)
we can take the slope between any 2 points (assuming the slope is the same, which it is)
(4,50) and (8,100)
slope=(100-50)/(8-4)=50/4=25/2=12.5
the slope is 12.5
2nd option is the answer

Answer:
It will take 55 years for the account value to reach 38200 dollars
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
.
In this problem, we ahve that:

So
First we find how much we have to earn in interest.
.


How much time to earn this interest?




Rounding up
It will take 55 years for the account value to reach 38200 dollars
