Mr. Frankel bought 5 tickets to a puppet show and spent $29. He bought a
combination of child tickets for $5 each and adult tickets for $7 each. Which system
of equations below will determine the number of adult tickets, a, and the number of
child tickets, c, he bought?
A. a = c-7
7a + 5c = 29
B.
a+c= 145
a +c= 5
C. 5a + 5c = 34
a+c=5
D.
7a + 5c = 29
a+c= 5
