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

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
