$18 %$ $18%$

Well the tip is the percentage profit..

$% p = \frac{s p - c p}{c p} \times 100$ $%p = (sp - cp)/(cp) xx 100$

$% p = percentage profit$ $%p = "percentage profit"$

$s p = selling price$ $sp = "selling price"$

$c p = cost price$ $cp = "cost price"$

$s p = $ 20$ $sp = $20$

$c p = $ 16.95$ $cp = $16.95$

Plugging in the values;

$% p = \frac{20 - 16.95}{16.95} \times 100$ $%p = (20 - 16.95)/16.95 xx 100$

$% p = \frac{3.05}{16.95} \times 100$ $%p = 3.05/16.95 xx 100$

$% p = 17.994$ $%p = 17.994$

$% p = 18$ $%p = 18$
