Mary Sue was a dedicated company employee. She worked for the same company for 32 years
(1986 to 2018). Mary Sue once noted βWhen I started working here in 1986, I was making $20,000.
Now Iβm making about $60,000!β
a) By what percent has Mary Sueβs salary increased over the years?
b) Inflation from 1986 to 2018 was about 130%, meaning increase $1 in 1986 by 130% to get its
equivalent value in 2018:
130% of $1: $1(1.3) = $1.30
Increase by 130%: $1 + $1.30 = $2.30.
So, $1 in 1986 has the same value as $2.30 in 2018.
Knowing this, what might someone say was Mary Sueβs βtrueβ percent increase in salary over
the years? (i. e., what is her percent salary increase when adjusted for inflation?).
