Question #01cc9

Answer 1

It is a `71.4%` increase

Explanation:

Any change in an amount can be given as a percent (of itself).

For example a change from 8 to 16 could be said as

"The amount doubled" which is the same as saying:
"An increase of 100%"

A change from 8 to 4 could be said as:

"The amount halved" which is the same as saying
"A decrease of 50%"

A change can be an increase, decrease, profit, loss, markup, discount etc. Use the same method:

`% "change" = "amount of change"/"original amount" xx 100%`

In this case the change was from `42 to 72`
This is an increase of `30`

% change = `30/42 xx 100%`

`=71.4%` increase
