The interest rate on a car loan has increased 50% over the last 10 years and is now 9%. what was the rate 10 years ago? (enter a percentage rounded to the nearest whole number)

lets suppose initial rate of interest we need to find =x

total rate of interest as 1.5x  (50%+ (consider 9% as)100%)in decimal it will be 1.5

Total rate of interest = current rate of interest

1.5x=9%

initial rate of interest  x= 9/1.5 =6  Answer

to check you can calculate  50% of 6 which will be 3 and later verify

Step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
