Jackie is reading a 252 page novel for her summer reading project. On Monday she reads 4/8 of the novel. On Tuesday she reads 28

natima [27]

So far, Jackie has read 217 pages

In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together

Number of pages she read on Monday = $\frac{4}{8}$ x 252 = 126 pages
Number of pages she read on Tuesday = 28 pages
Number of pages she read on Wednesday = $\frac{1}{4}$ x 252 = 63 pages

The total number of pages she has read so far = 126 + 28 + 63 = 217 pages

3. Formulate 900 lbs of a 35% CP ration using Soybean Meal (46% CP) and Oats (12% CP). How many pounds of soybean meal will be u

Anarel [89]

Answer:

The amount of Soyabean = 608.82 pounds.

The amount of Oats = 900-608.82 = 291.18 pounds.

Step-by-step explanation:

Given that the Soybean Meal has 46% CP and Oats has 12% CP.

The total amount of ration is 900 lbs of 35% CP.

Let x pounds of Soyabean has been used, so,

the amount of Oats = 900-x lbs.

The CP amount in 900 lbs mixture will be equal to the sum of CP amounts in x lbs Soyabean and 900-x lbs Oats, i.e

35% of 900 = 46% of x + 12% of (900-x)

$\Rightarrow \frac{35}{100}\times 900=\frac{46}{100}\times x+\frac{12}{100}\times (900-x)$

$\Rightarrow 35\times 900 = 46x + 12\times 900 - 12 x$

$\Rightarrow 34x= 900(35-12)$

$\Rightarrow x = (900\times 23)/34$

$\Rightarrow x = 608.82$ lbs.

So, the amount of Soyabean = 608.82 pounds.

The amount of Oats = 900-608.82 = 291.18 pounds.
