Last saturday, the museum box office sold 281 tickets for a total of $3,954. adult tickets cost $15, and student tickets cost $12. how many of each kind of ticket were sold?

If all were student tickets, revenue would be 12·281 = 3372. It is actually 3954-3372 = 582 more than that. Each adult ticket sold increases revenue by $3, so there must have been 582/3 = 194 adult tickets sold. Then 87 student tickets were sold.

87 student and 194 adult tickets were sold.

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%

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
