Question

The number of trucks registered in a city each year increases by 10% each year. initially there were 100 trucks registered.

Use a function T(r) that represents the number of trucks registered in the city in year r.
What is the number of trucks registered in the city in year 8?
Round your answer to the nearest whole number
UPDATE: 214

Answer 1

let "r" represent the years, in this equation to solve the compounded amount of trucks.

Total Trucks = 100(1.1)^r

After 8 years, the answer would be 214.35. This is how to calculate compound interest questions.
