Brianna has a gift card for $15 that she will use to help buy a new pair of jeans. The jeans that she wants were originally priced at $62.80, but this weekend they are marked down 25% as part of a back-to-school sale. Also, because of a sales tax holiday, Brianna will not have to pay any sales tax on the jeans. How much will Brianna have to pay for the jeans, after the value of the gift card has been deducted? $0.70
$32.10
$35.85
$47.10

32.10

Step-by-step explanation:

25% of 62.80 is 15.70

62.80- 15.70 = 47.10

47.10- the 15 dollar giftard = 32.10

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

step-by-step explanation:

the answer is 128
