Answer:
Michelle's age = 16
Step-by-step explanation:
As we know,
Amount = where
P = Principal amount
r = rate of interest
t = time
Given ,
P = $1000
r = 4.5 % =
Now,
Given that Amount reaches more than $2000
⇒ > 2000
⇒ > 2000
⇒ > 2
Now,
we put the value of t from 0 , 1, 2, ..... untill the above equation does not satisfy
Now,
for t = 0
for t = 1
for t = 2
for t = 3
for t = 4
for t = 5
for t = 6
for t = 7
for t = 8
for t = 9
for t = 10
for t = 11
for t = 12
for t = 13
for t = 14
for t = 15
for t = 16
It satisfies at t= 16
∴ we get
Michelle's age = 16
