At the movie theater the prince on 1 adult ticket and 4 child tickets is $44 the price of 5 adults tickets and 2 child tickets i

nydimaria [60]

The cost of one adult ticket is $12 and cost of one child ticket is $8.

Step-by-step explanation:

Let,

Cost of one adult ticket = x

Cost of one child ticket = y

According to given statement;

x+4y=44 Eqn 1

5x+2y=76 Eqn 2

Multiplying Eqn 1 by 5

$5(x+4y=44)\\5x+20y=220\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(5x+20y)-(5x+2y)=220-76\\5x+20y-5x-2y=144\\18y=144$

Dividing both sides by 18

$\frac{18y}{18}=\frac{144}{18}\\y=8$

Putting y=8 in Eqn 1

$x+4(8)=44\\x+32=44\\x=44-32\\x=12$

The cost of one adult ticket is $12 and cost of one child ticket is $8.

A group of college students were asked about their TV watching habits. Of those surveyed, 30 students watch The Walking Dead, 24

Usimov [2.4K]

Answer: 44 students

Step-by-step explanation:

Let Walking dead be denoted as W

Let Blacklist be denoted as B

Let Game of thrones be denoted as G

Total number of students that watch W = 30

W&G&B = 7

W&B only = 13-7 = 6

W&G only = 10-7 = 3

To get the number of people that watch W ONLY, we subtract those that watch W&B only (6), W&G only(3) and W&B&G(7) from 30. Hence,

W Only = 30 - 6- 3 - 7= 14 (14 students watch Walking dead only)

Total number of students that watch B =24

B&G&W = 7

B&W only = 13-7 = 6

B&G only = 16 - 7 = 9

Hence, those that watch B only = 24-6-9-7= 2 students.

Total number of students that watch G = 22

G&W&B = 7

G&B only = 9

G&W only = 3

Hence those that watch G only = 22-9-3-7 = 3 students.

Hence number of students that watch at least one show = W only + B only + G only + W&B only + W&G only + B&G only + W&B&G.

= 14+2+3+6+3+9+7 = 44 students.
