The shirt was doubly marked down! There was a 25% off sale, and then an additional 10% off of that. After the mark downs, the price was $30. Which equation shows the original price of the shirt? Use S to represent original price of shirt.

40.5

Step-by-step explanation:

i multiplied 30 with .25 which was 7.5

then i multiplied 30 with .1 which was 3

add those together 10.5

add that too 30 which is 40.5

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%
