Plug in 2 for x. f(20=2-51 = -49
Answer:
95 child tickets
Step-by-step explanation:
a+c =153 c=( 153-a) you need to plug this for c
9.6a + 5.6(153-a) = 1088.8
9.6a + 856.8 - 5.6a = 1088.8
4a +856.8 = 1088.8
subtract 856.8 on both sides
4a = 232
a=58 (58 adults)
153 - 58 = 95 (95 children)
95*$ 5.6 = $532
85 *$ 9.6 =$ 556.8
$532 + $556.8 =$ 1088.8
(6a+11)=(2a+83)
6a+11=2a+83
-11 -11
6a=2a+72
-2a -2a
4a=72
4/4a=72/4
a=18
The solution is 18
Allen because 15% of 56=0.15 times 56=8.4
