$349.30 because u multiply the cost of 1 case times 14 the # of cases
4 adult tickets were sold and 8 student tickets were sold.
How did I get this?
First, let's see what information is given:
12 tickets sold
(S)tudent ticket = $9
(A)dult ticket = $12
Total cost = $120
So, we know student tickets plus adult tickets total up to $12. We can create an equation out of this: S + A = 12
And we know $9S + $12A = $120
The variables represent the amount of tickets sold, which is unknown.
A = 12 - S , substitute this into the second equation.
9s + 12(12-s) = 120
Distribute the 12 into the parenthesis.
9s + 144 - 12s = 120
Combine like terms
-3s + 144 = 120
Subtract both sides by 144, left side cancels out.
-3s = -24
s = -24/-3
s = 8
So, 8 student tickets were sold. Plug the value of s into our first equation.
A = 12 - 8
A = 4 (adult tickets)
Answer:
Step-by-step explanation:
y + 1 = 3(x - 2)
y + 1 = 3x - 6
y = 3x - 7
Evaluating functions means to substitute the values at every occurrence of x.
So, we have
