Jeremy received a bill with a balance due of $25.60. After an error was corrected, the new balance due was 1/4 of the original balance due. What was the balance due?

$6.40

Step-by-step explanation:

Jeremy received a bill that was $25.60.

This was wrong and the actual amount due was 1/4 of the above figure.

The actual figure must therefore be:

= 25.60 * 1/4

= $6.40

answer: d. $20

step-by-step explanation:

just took the test

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%
