Answer:
21 child tickets
Step-by-step explanation:
For this problem, you'd use a system of equations.
First, define your variables.
x = # of child tickets sold
y = # of adult tickets sold
There were 4 times as many adult tickets (y) as child tickets (x) sold, so:
4 x = y
4 x - y = 0
93 (4 x - y = 0)
372 x - 93 y = 0
The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:
6.10 x + 9.30 y = 909.30
10 (6.10 x + 9.30 y = 909.30)
61 x + 93 y = 9093
372 x - 93 y = 0
433 x = 9093
433 x / 433 = 9093 / 433
x = 21
Answer:
7
Step-by-step explanation:
The formula for surface area of a triangular prism is
SA = 2(L)(W) + 2(W)(H) + 2(H)(L) * 1/2
SA = 2(3)(2) + 2(2)(4) + 2(4)(3) * 1/2
SA = 12 + 16 + 24 * 1/2
SA = 52 *1/2
SA= 26sq in
I hope this helped!:)
