A + c = 824 represents number of tickets to sell
20a + 12c = 13,344 represents cost of each type of ticket
multiply equation 1 by -12 to cancel the variable 'c' and solve for 'a'
-12(a + c = 824)
-12a - 12c = - 9888
20a + 12c = 13,344 add equations together
-----------------------------
8a = 3456 divide both sides by 8
a = 432
To find children's tickets substitute adult numbers back into equation 1.
a + c = 824
432 + c = 824
subtract 432 from both sides
c = 392
adult 432, children 392
Answer:
zero and negative four
I hope that's what you meant I don't know
Step-by-step explanation:
f(x) = -(x - 2)
=-(2-2)
=0
f(x) = -(x - 2)
=-(6-2)
=-4
Step-by-step explanation:
This can be modeled by the equation f(x)=7+5x
Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22
If x=50 then f(50)=7+5(50)
f(50)=$257
