Answer:
=2277 Ans.
Step-by-step explanation:
Find the selling price
(a) Cost =600
Profit=13%
Selling price =Cost + profit
=600+
100
600×13
=600+78
=678 Ans.
(b) Cost=2475, loss=8%
Selling price = Cost+ profit/loss
=2475+(−
100
2475×3
)
=2475−198

Problem
Henry purchased compact disks for $112. The compact discs cost $16 each.
Which of the following equations could you use to find how many compact disks, x, Henry purchased?
Solution
We can set up the following notation:
x= number of disks
total cost = (number of disks)* (unitary price)
Total cost = $112
number of disks =x
unitary price = $16
Replacing we got:
112 = x*16
For this case the correct equation would be given by:
$112 = $16x
<u>40% of 300 </u>
<u>=300×(40/100) </u>
<u> [As40 percent means 40 out of hundred, so we need to multiply the fraction]</u>
<u>=3×40</u>
<u>=120 </u>
<h3><u>
40% of 300 =120 So 120 students choose conserving natural resources.</u></h3><h3><u>
</u></h3><h2><u>
2.</u></h2>
<u>Now 24% choose conserving natural resources ,</u>
<u>24% of 300</u>
<u>=300(24/100)</u>
<u>=3×24</u>
<h2><u>
=72</u></h2><h3><u>
So 72 students choose conserving natural resources.</u></h3>
