L = Lower box tickets amount.
U = Upper box tickets amount.
we know the whole amount sold were 254 of both, thus
L + U = 254.
since we know the price of L is 12.5 for each, then the amount of money sold total for all of them has to be 12.5 * L, or
12.5L.
and the U is 10, so its total amount of money for it is
10U.
we also know that the total amount for both spent was 2745, thus
12.5L + 10U = 2745.

so, 172 Upper box tickets were sold then.
how many Lower box tickets were sold? well,
L = 254 - U
Answer:
The probability of not selecting a red marble, P(R)' = 10/19
Step-by-step explanation:
The probability of an event occurring is equal to the number of ways the required event occurs divided by the number of possible outcomes
The number of ways of an event not occurring is 1 less the probability of the event occurring
The number of green marbles in the bag = 6
The number of red marbles in the bag = 9
The number of blue marbles in the bag = 4
The sum of the marbles in the bag, n = 6 + 9 + 4 = 19
The number of ways of selecting a red marble = 9 ways
The probability of selecting a red marble = 9 ways/19 marbles = 9/19
The probability of not selecting a red marble = 1 - 9/19 = 10/19 = 
The probability of not selecting a red marble P(R)' = 10/19

Answer:
answer is 4.
Step-by-step explanation:
the difference between 5 and 9 is 4
9-5=4
