Question

A factory produces 1,250,000 toys each year. The number of toys is expected to increase by about 150% per year. Which model can be used to find the number of toys being produced, n (in millions), in t years?

Answer 1

`N= 1250000(1+ (150)/(100)) ^(n)`

Answer 2

N= 1250000(2.5)^t

Explanation:

A factory produces 1,250,000 toys each year. The number of toys is expected to increase by about 150% per year

For exponential growth we use equation

N=a(1+r)^t

'a' represents initial number of toys= 1250000

'r' represents the increase percentage 150%= 150/100

N=a(1+r)^t

N= 1250000(1+150/100)^t

N= 1250000(1+1.5)^t

N= 1250000(2.5)^t
