Mary is traveling cross country on a road trip. so far, mary has traveled 200 miles in her car and 200 miles by train. the car traveled at a rate that was 30 miles per hour slower than the train. what does x - 30 represent in this situation?

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%

215.92 dollars is the answer
