Answer:
for adult tickets 90 and for children’s tickets 30
Step-by-step explanation:
because 90(18) = 1,620 and 30(12) is 360 and when you add up 1,620 + 360 you will get the total which is $1980
Also i just took the test on k12 and got it right and i hope this helps!
Only a guess but 69.5 7

Answer:
-15.96
Step-by-step explanation:
A conjugate is a binomial with the sign inside changed. So the conjugate of (1/5 + 4i) is (1/5 - 4i)
Set the original and the conjugate next to each other and F.O.I.L. Multiply the first numbers of each binomial, the 1/5 and the 1/5 to get 1/25. This is the "F."
Multiply the outer members, the 1/5 and the 4i to get - 60i. This is the "O."
Multiply the inner numbers ( the + 4i and the 1/5) to get + 60i. This is the "I."
Multiply the positive 4i and the negative 4i to get 16i squared
The positive 60i and the negative 60i cancel each other out.
The i squared changes into - 1. This makes the 16 negative.
Add 1/25 to - 16 to get - 15.96
If they manage to sell
tickets, they will earn
dollars. We want this number to be at least 1000, so the inequality would be

In order to solve this for t, you only need to divide both sides by 15:

So, they need to sell at least 67 tickets to have an income of
dollars
