Answer 1

Answer:

5.  $40

6.  500 students

7.  60 books

8.  63 pages

Step-by-step explanation:

Question 5

Given:

• Aiden spent $18 on souvenirs.
• $18 is 45% of the money he brought on the trip.

Let x be the money Aiden brought on the trip.

Create equivalent ratios with the given information and defined variable, and solve for x:

$\implies 18:45\%=x:100\%$

$\implies 18:0.45=x:1$

$\implies \dfrac{18}{0.45}=\dfrac{x}{1}$

$\implies 18=0.45x$

$\implies x=\dfrac{18}{0.45}$

$\implies 40$

Therefore, Aiden brought $40 on the trip.

Question 6

Given:

• Angel received 300 votes.
• 300 votes was 60% of all the votes.

Let x be the number of students who voted in the election.

Create equivalent ratios with the given information and defined variable, and solve for x:

$\implies 300:60\%=x:100\%$

$\implies 300:0.6=x:1$

$\implies \dfrac{300}{0.6}=\dfrac{x}{1}$

$\implies 300=0.6x$

$\implies x=\dfrac{300}{0.6}$

$\implies x = 500$

Therefore, there were 500 students who voted in the election.

Question 7

Given:

• The students sold 80% of the books.
• The total number of books they sold is 48.

Let x be the number of books in the sale.

Create equivalent ratios with the given information and defined variable, and solve for x:

$\implies 80\%:48=100\%:x$

$\implies 0.8:48=1:x$

$\implies \dfrac{0.8}{48}=\dfrac{1}{x}$

$\implies 0.8x=48$

$\implies x=\dfrac{48}{0.8}$

$\implies x=60$

Therefore, there were 60 books in the book sale.

Question 8

Given:

• Aiyana read 147 pages of the book.
• She completed 70% of the book.

If she has completed 70% of the book, then she still has 30% left to read, as 100% - 70% = 30%.

Let x be the number of pages Aiyana still has to read.

Create equivalent ratios with the given information and defined variable, and solve for x:

$\implies 70\%:147=30\%:x$

$\implies 0.7:147=0.3:x$

$\implies \dfrac{0.7}{147}=\dfrac{0.3}{x}$

$\implies 0.7x=44.1$

$\implies x=\dfrac{44.1}{0.7}$

$\implies x=63$

Therefore, Aiyana still has 63 pages left to read.
