Answer:
<em>6). 7 years , 29 members ; 7). $5 is the price of the child movie ticket, $15 is the price of the adult movie ticket. </em>
Step-by-step explanation:
<em>6).</em> y = 50 - 3x
y = 15 + 2x
15 + 2x = 50 - 3x
5x = 35
x = <em>7 years</em>
y = 15 +2(7)
y = <em>29 members</em>
In 7 years game club and sport club will have 29 members.
<em>7).</em> 2a + 3c = 45 ......... (1)
2a + 2c = 40 ......... (2)
(1) - (2)
c = <em>$5 is the price of the child movie ticket</em>
2a + 2(5) = 40
a = <em>$15 is the price of the adult movie ticket</em>
$639.20
She earns $5 an hour plus 4%
4% of 12,480 is $499.20
$5*28 hours is $140
$499.20 + $140 = $639.20
