Awnser: $13 each ticket
Explaination:
In total he spend $87 which means you have to subtract $22 which equals $65 and you divide that by 5 because of his four friends and himself. Which ends up being $13
Okay so you would subtract the 30 to get 210 then divide the 210 by 14 to get 15 so your inequality

your original inequality is

Nadia surveyed 80 students at her school and found the following results:
=> 0.55 of the students she surveyed said their favorite class is math.
=> 15% of the students <span>she surveyed reported that their favorite class is science.
Let's find out many more students in the survey prefer math over science?
MATH
=> 80 students * 0.55 = 44 students love math.
SCIENCE
=> 80 * .15 = 12 students love science
</span>=> 44 - 12 = 32 students
B. 32
<u>Answer:</u>
A) 720 ways
B) 15 ways
C) 6 ways
<u>Step-by-step explanation:</u>
A) To find the number of ways Alicia can arranger her 6 paintings, we will find factorial of 6 by multiplying all of the positive integers equal to or less than that number i.e. 6 to get:
6! = 6 * 5 * 4 * 3 * 2 * 1 = 720
Alicia can arrange her paintings in 720 ways.
B) We use the following formula (when order is not important) to find the number of permutations of n objects taken r at a time:


Therefore, Alicia can choose any 4 of her paintings in 15 ways.
C) Number of ways Alicia can arrange 3 out of 6 paintings = 3! = 3*2*1 = 6 ways
