You have to simplify like this
(-5)(-8)=40
$40 minus the $2 for the water bottle = $38 minus the $20 he has remaining = $18 divided by the 4 water bottles he bought = 4.5 which is $4.50
Answer:
15% or 3/20
Step-by-step explanation:
25 in class and 10 are girls so probability of first choice being a girl is 10/25.
Then for the second pick there are 24 students and 9 are girls so the probability is 9/24. You multiply 10/25 by 9/24 to get your answer.
Answer: x = # of student tickets
y = # of adult tickets
x + y = 1294 >> y = 1294 - x
5x + 8y = 8816
5x + 8y = 8816
5x + 8(1294 - x) = 8816
5x + 10,352 - 8x = 8816
-3x + 10,352 = 8816
-3x = -1536
x = 512 student tickets
512 student tickets were purchased.
