Question

The number of trucks registered in a city increases by 10% each year. Initially, there were 100 trucks registered. There were 110 trucks registered at the end of Year 1.

What is the number of trucks registered in the city at the end of Year 8?

Answer 1

214

Explanation:

I took the test and got 100%

Answer 2

214 trucks

Explanation:

Un= amount after a certain time period

Uo= initial amount

n= number of time periods

i= interest rate

Equation used : Un= Uo (1+i)^n

Un=100(1.1)^8 = 214.36 , but you can't have half a truck so round and the answer would simply be 214.
