Rhonda wants to buy a shirt that is on sale for 15% of the regular price. The regular price of the shirt is P dollars. Which expression represents the sales price of the shirt? A. p-0.15p
B. p+0.15p
C. p-15p
D. 0.15p

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
