$16 + \frac{15}{100} \times 16 or \frac{115}{100} \times 16$ $16 + 15/100 xx 16" or "115/100 xx16$

Explanation:

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

New price = $16 + \frac{15}{100} \times 16$ $16+15/100 xx 16$

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

New price = $\frac{115}{100} \times 16 = 1.15 \times 16$ $115/100 xx 16 = 1.15xx16$
