Answer:
y+x=31, 150x+225y=5100.
y=-x+31
150x+225(-x+31)=5100
-75x=-1875
x=25 (adult tickets are $25)
31-25= 6 (child tickets are $6)Step-by-step explanation:
Answer:
The answer to your question is x = 23.36
Step-by-step explanation:

Solve for x
1250 = 500(1.04)

Apply logarithms

log 2.5 = x log 1.04
x = 0.398 / 0.017
x = 23.36
Answer:
Step-by-step explanation:
Given that events are as follows:
A: A green ball is drawn from a box with five balls and placed next to the box. B: A red ball is drawn next and placed next to the green one
i.e. drawings of balls are made without replacement
Suppose there are m green balls and n red balls, where m+n =5
Prob of drawing green ball =m/5
After I draw made remaining are n red balls and m-1 green balls
Prob of drawing red ball now =n/4
Prob for drawing one green and one red simultaneously = 
Product of the two probabilities =
