Is you do the answer first 725 times 493 it would equal 357,425
then i just did lana first because it was easy and it came out to 357,425
tamir way of solving the problem was wrong equaling 281,815
First we are gonna find the 3% of $3000 and take it from the $157.50.
3000 x 0.03 = $90
157.60 - 90 = $67.50
Then we are gonna find the amount that 4.5% of is equal to $67.50.
4.5/100=67.50/x (cross multiply)
4.5x = 67.50x100
4.5x = 6750 (divide both sides by 4.5)
4.5x/4.5 = 6750/4.5
x = 1500
Therefore the amount she earned in sales is $3000 + $1500 = $4500
divide the total cost ($192.00) with the number of children (16):
$192.00 : 16 = $12
the cost is $12 per child.
The maximum and minimum percent of students who write their notes with a pencil are 22% and 25%, respectively
<h3>Survey</h3>
The survey results given as:
--- the proportion of students reported that they wrote their notes with a pencil
<h3>Range</h3>
The range is then calculated as:
<h3>Minimum</h3>
So, we have:
This gives
<h3>Maximum</h3>
Also, we have:
This gives
Hence, the maximum and minimum percent of students who write their notes with a pencil are 22% and 25%, respectively
