It depends on how many students there are in Mr. Edwards class
Given:
Rate of interest = 8% compounded continuously.
Amount = 100,000
Time = 25 years
To find:
The principal value.
Solution:
Formula for amount after continuous compound interest:

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting
in the above formula, we get




On further simplification, we get

Therefore, the amount 13533.528 is invested.
Answer:
y = 7/2 -2
Step-by-step explanation:
if the slope of the first problem is -2/7 then its perpendicular is 7/2 (the exact opposite) and since the y- intercept is the b in Y= mx +b the intercept of the equation you’re trying to find is -2
First you need to figure out the slope:
y2-y1/x2-x1=(1+5)/(-5-7)=-1/2
y+5=-1/2(x-7)
y=-1/2x-3/2
2.57 is the anwser. it comes out to be 2.56666667 which woukd round up to 2.57
