Atheater sells adult tickets for $8.00 and children’s tickets for $5.50

Let Total = t, adult tickets = a, children's ticket = c, total cost = T

t = a + c

T = 8a + 5.50c

is your system equation.

hope this helps

If there are 14 different scenarios that can happen (Blue 1-5, Green 1-6, Red 1-3), and 9 of them are not blue, there is a 9/14 chance that the first pick is not blue. to get percentages, you divide 9 by 14 to get 0.64, or 64 percent chance at not picking blue.
