Question

Last year there were m members in a photography club. This year the number of

members has increased by 10%. The expression m + 0.1m represents the number of
members in the club this year. What is this expression written in simplest form?

Answer 1

m + 10/100(m)

Explanation:

• Last year there were m members in a photography club.
• This year the number of members has increased by 10%
• m + 0.1m represents the number of members in the club this year.

So m represents the number of members in the club last year.

A 10% increase of the members =
`(10)/(100) * m` = 0.1m

Hence the number of members in the club this year = m + 0.1m
