Zepler [3.9K]

Answer:

Cost price of each candy = $0.80, Selling price of each candy = $1.40

Step-by-step explanation:

Given:

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%.

He sells each candy var for 175% of what he paid before tax.

Question asked:

How much does he buy each candy bar for ?

How much does he sell one for ?

Solution:

<u>By unitary method:</u>

Cost of 50 packs of candy bars = $40

Cost price of 1 pack of candy bars = \frac{40}{50} =\$0.8

Cost price of each candy = $0.80

Thus, he buy each candy bar for $0.80

Now:-

As he sells each candy var for 175% of what he paid before tax:-

Selling price of each candy = 0.80 \times 175%

                                              = 0.80\times\frac{175}{100} =\frac{140}{100}=\$1.4

Thus, he sell one candy for $1.40

Elisabeth reads 1/5 of her book in 1 1/2 hours. Elisabeth continues to read at this pace. How long does it take Elisabeth to rea
djverab [1.8K]

It will take her  5 5/8 hours to read 3/4 of the book

<h3>Ratio and proportions</h3>

Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:

0.2 of a book = 1.5 hours

In order to determine the time taken to read 0.75 part of the book, we will have:

0.75 of a book  = x

Take the ratios

0.2/0.75 = 1.5/x

0.2x = 1.125

x = 1.125/0.2

x =  5.625

Hence it will take her  5 5/8 hours to read 3/4 of the book
