Answer:
6). 7 years , 29 members ; 7). $5 is the price of the child movie ticket, $15 is the price of the adult movie ticket.
Step-by-step explanation:
6). y = 50 - 3x
y = 15 + 2x
15 + 2x = 50 - 3x
5x = 35
x = 7 years
y = 15 +2(7)
y = 29 members
In 7 years game club and sport club will have 29 members.
7). 2a + 3c = 45 ......... (1)
2a + 2c = 40 ......... (2)
(1) - (2)
c = $5 is the price of the child movie ticket
2a + 2(5) = 40
a = $15 is the price of the adult movie ticket
