Answer:
<em>Number of story books bought = 100
</em>
<em>
C.P. of each book = Rs. 135
</em>
<em>
C.P. of all 100 books = Rs. (135×100)= Rs. 13500
</em>
<em>
C.P. of 90 books = Rs. (135×90)= Rs. 12150
</em>
<em>
Number of books donated = 10
</em>
<em>
Number of books sold = 100-10=90
</em>
<em>
Loss% in the transaction = 2%
</em>
<em>
S.P. of all books = (C.P./100)(100-loss%)
</em>
<em> =Rs. (12150/100×98)
</em>
<em>
Thus, S.P. of each book
</em>
<em>
= Rs. {(12150/100×98)÷90}
</em>
<em>
= Rs. (12150/100×98/90)
</em>
<em>
= Rs. 132.3</em>
1 is incorrect. to solve for f, you have to get it alone, and right now you have a negative sign in your way.
you can eliminate the negative by dividing both sides by -1:
-f = -100
divide by -1 to cancel out the - in front of f
f = 100

Answer:
B). -3
add the -1.4 to-3.5 then divide the solution
Since approximately 95% of any normal distribution falls within two standard deviations of the mean, it follows that 5% falls outside that range, with 2.5% to either side. So
.
The actual value is a bit closer to 0.0228, but that's not very far off.
