B. (6 * 5) + (4 * 10)
If there are six members that each cost five dollars, then you know a part of the equation is (6 * 5)
Likewise, if there are four non members that each spend ten dollars on tickets, the other part of the equation should be (4 * 10)
Then, to get the total amount of money spent, you would need to add these two mathematical statements together:
(6 * 5) + (4 * 10) is your answer

If there are twenty white marbles in a bag of 40, then the chances of drawing a white marble is 20/40, or 0.5: one chance in two of drawing white.
Answer:
Option 3 and 5
Step-by-step explanation:
Albert´s ftather age=x
Albert age=y
We suggest this system of equations:
y=x-24
x+8=2(y+8)
we solve this system of equation by substitution method.
x+8=2[(x-24)+8]
x+8=2(x-16)
x+8=2x-32
x-2x=-32-8
-x=-40
x=40
y=x-24
y=40-24
y=16
Answer: Albert´s father is 40 years old, and Albert is 16 years old.
