Answer:

So Price after discount would be 17.5 on February 1st

Step-by-step explanation:

Given:

Original Cost =57.75

Off Price = 70%

To Find:

Price after discount = ?

Solution:

We have to find the price after discount which is given by the formula

Price after Discount = Original Cost - Discount Price

We have to find the value of discount price

Discount Price = off Price * Original Cost

Putting in the values

Discount Price = 70 % * 57.75

it becomes

Discount Price $=\frac{70*57.75}{100}$

It becomes

$=\frac{4025}{100}$

= 40.25

Now

Price after Discount = Original Cost - Discount Price

Putting in the values

it becomes

Price after Discount = 57.75-40.25

= 17.5

So Price after discount would be 17.5 on February 1st

Refer to the following distribution:Cost of Textbooks Frequency $25 up to $35 2 S35 up to $45 5$45 up to $55 7$55 up to $65 20 S

soldi70 [24.7K]

Answer:

$Relative\ Frequency = 0.04$

Step-by-step explanation:

Given

Cost of Textbooks ---- Frequency

$25 up to $35 ----- 2

$35 up to $45 ------- 5

$45 up to $55 ------- 7

$55 up to $65 ------ 20

$65 up to $75 ---- -- 16

Required

Determine the relative class frequency for the $25 up to $35 class

First, we need to get the total frequency

$Total = 2 + 5 + 7 + 20 + 16$

$Total = 50$

Next, is to write out the frequency of $25 up to $35 class

$Frequency = 2$

Divide this frequency by the total frequency; This gives the relative frequency

$Relative\ Frequency = \frac{Frequency}{Total}$

$Relative\ Frequency = \frac{2}{50}$

$Relative\ Frequency = 0.04$

Hence;
