Yolanda purchased a prepaid phone card for $20. long distance calls cost 14 cents a minute using this card. yolanda used her card only once to make a long distance call. if the remaining credit on her card is $14.12, how many minutes did her call last?

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%
