Formula for amount for compound interest:
Amount, A = P(1 + r/100)^n
Where r is rate, P is principal, and n is the number of years.
P = 2000, r = 5, n = t years.
A = 2000( 1 + 5/100)^t
A = 200(1+0.05)^t
A = 2000(1.05)^t
A(t) = 2000(1.05)^t
None in the option look like the answer we have.
Except you didn't type the last option correctly.
Answer:
3
Step-by-step explanation:
First we must find the total boxes of pens
15 + 9 = 24
Then we can divide the total cost by the total number of boxes of pens
$72 / 24 boxes = 3
Your answer would be 15 m if i’m doing it right
Assuming you don't know the exact numbers, we can sequentially figure out the number of inches in a mile and seconds in a day
Inches in a mile:
There are 5280 feet in a mile.
5280*12 = 63360 inches in a mile
Seconds in a day:
There are 24 hours in a day
There are 24*60 = 1440 minutes in a day
There are 1440*60 = 86400 seconds in a day
There are more seconds in a day than inches in a mile.
