Question

At the start of 2014 Tim's house was worth 100,000.

The value of the house increased by 10% every year.

Work out the value of his house at the start of 2018

Answer 1

For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
y = 100000 * (1.10) ^ 4
y = 146410
Answer:
the value of his house at the start of 2018 is:
y = 146410
