Answer:
Interest earned= $6,060
Step-by-step explanation:
Giving the following formula:
Principal (P)= $12,625
Interest (r)= 4%= 0.04
Period of time (t)= 12 years
<u>To calculate the interest earned after twelve years, we need to use the following formula:</u>
I= P*r*t
I= (12,625*0.04*12)
I= $6,060
Interest earned= $6,060
The answer is: (4,0), (0,4)
Answer:
The approximate cost during the year 1987 was $7,533
Step-by-step explanation:
The complete question in the attached figure
we have
y -----> is the cost in dollars
x -----> is the year
Looking at the graph we have the points
(1983,5,047) and (1991, 10,019)
To determine the cost in the year 1987, find out the midpoint between the two given points
The formula to calculate the midpoint between two points is equal to

substitute the values


therefore
The approximate cost during the year 1987 was $7,533
The answer for this question that needs an answer is n = 5
because 18(n-1) = 9(n+7) implies that 18n - 18 = 9n + 63 which implies that n =5 for the equation to hold true.
