Answer:

84 dollars

Step-by-step explanation:

use x to represent the amount of money Laura had when she started shopping.

use y to represent the amount of money she had left after buying a pair of shorts.

You can create these two equations:

3/4x=y

2/3x=42

now, subsitute the value of y into the second equation.

2/3(3/4x)=42

1/2x=42

x=84

A local anime fan club surveyed its members regarding their viewing habits last weekend, and the following information was obtai
DiKsa [7]

Answer:

a) 83.099% of the club members had watched Naruto or Death Note.

b) 15.493% of the club members had watched only Naruto

c) 33.803% of the club members had watched only Death Note.

Step-by-step explanation:

First we find the number of students which each habit, treating the habits as Venn sets.

I am going to say that:

Set A: Watched an episode of Naruto.

Set B: Watched an episode of Death Note.

24 had watched both an episode of Naruto and an episode of Death Note:

This means that (A \cap B) = 24

48 had watched an episode of Death Note

This means that B = 48.

We have that:

B = (B-A) + (A \cap B)

In which B - A are those who watched only Death Note. So

48 = (B-A) + 24

(B-A) = 24

35 members had watched an episode of Naruto

This means that A = 35.

A = (A-B) + (A \cap B)

35 = (A-B) + 24

(A-B) = 11

At least one:

This is

(A \cup B) = A + B - (A \cap B)

So

(A \cup B) = 35 + 48 - 24

(A \cup B) = 59

Total number of students:

59 at least one, 12 none, so 71 total.

(a) What percent of the club members had watched Naruto or Death Note?

At least one, so 59 out of 71

59*100/71 = 83.099

83.099% of the club members had watched Naruto or Death Note.

(b) What percent of the club members had watched only Naruto?

11 out of 71. So

11*100/71 = 15.493

15.493% of the club members had watched only Naruto.

(c) What percent of the club members had watched only Death Note?

24 out of 71. So

24*100/71 = 33.803

33.803% of the club members had watched only Death Note.
