Question

A plant is 30cm tall when planted in a garden it increases by 10 percent each week how long will it take to reach 1 meter

Answer 1

Prob around 12 weeks. Just times it by 1.01 and keep repeating it

Answer 2

12.63 weeks ~~ 13 weeks

Explanation:

This is much like a banking question with compounded interest

FV = PV ( 1 + i)^n FV = Future value = 1 m PV = present value = .3

i = periodic interest = .10 n = periods

1 = .3(1 + .1)^n solve for n = the number of weeks

1/.3 = 1.1^n

log (1/.3) / log 1.1 = n = 12.63 weeks
