equations could be used to find a, the number of adult tickets, and c, the
number of children tickets that were purchased?
A. a+c= 345
45a +30c = 10

B. a+c= 345
30a +45c= 10

C.a+c= 10
30a + 45c = 345

D. a+c=10

Answer:

D

Explanation:

The answer is d, because a represents adults, and c represent children. It's $45 per adult, so $45a, and $30 per child, so $30c. a+c is equal to 10, because that's how many tickets were purchased. $45a+$30c=345, because $345 is the total amount spent on tickets.
