Question

If 45 is increased to 69, what is the percent increase?

Answer 1

`53.bar(3) %`

Explanation:

The increase is:

`69-45 = 24`

which as a percentage of the original value `45` is:

`24/45 * 100 = 2400/45 = (color(red)(cancel(color(black)(5)))*480)/(color(red)(cancel(color(black)(5)))*9) = 480/9 = 53.bar(3) %`
