Check the picture below.
now, since we know what "f" is, let us use the CNT triangle with the small COR one.
See the pic for the answer. You just multiply each term on the left by each term on the top. The coefficient is just the number in front of an unknown.
Answer:
Step-by-step explanation:you would multiply all the side then I would divide how many sides there are
The answer is letter D. Just take out the -1, then factor regularly
Let say the number of the months is t, the total amount of depo is a and a0 is the initial amount of money deposited. You can put it like this:
a= f(t) = a0 + x*t
You can solve the equation by inserting two of any t value. If you use f(8)-f(4) it will be
a0+ x(8)= 2500
a0+ x(4)= 1500
___________-
8x- 4x= 1000
4x= 1000
x=250
Then the new equation would be:
a= a0 + 250*t
Putting f(4) value you can find a0
1500= a0+ 250*4
a0=1500-1000=500
The final equation would be
a= 1000+ 250*t
