Question

The price of a flash drive that regularly sells for $16 is increased by 15%. How do you write two different expressions to find the new price?

Answer 1

`16 + 15/100 xx 16" or "115/100 xx16`

Explanation:

The new price can be found by working out how much `15%` of `16` is first and then adding it on to `$16`

New price = `16+15/100 xx 16`

te new price can also be found by adding `15%` on to `100%` and then finding `115%` of `$16`

New price = `115/100 xx 16 = 1.15xx16`
