The official run time of a movie is 140 minutes. your friend who has seen the movie says its about 2.3 hours
a. write the official run time in hours as a fraction and as a decimal.
b. did your friend overestimate or underestimate the length of the movie? illustrate your answer using tow different comparisons. which method did you prefer

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
