The first step to solve this problem, you have to compute
first for the total number of students:
6 math classes x 27 students per class = 162 students
Now, you know that there are 162 students all in all in the
school. The next step is to compute for the total cost of both the book and the
calculator per student.
$45.10 (Book) + $57.80 (Calculator) = $102.90 (total cost
per student)
To compute for the total cost that the school will pay, you
have to multiply the total cost per student to the number of students in
school.
$102.90 per student x 162 students = $16,669.80
Therefore, the total cost the school will pay is $16,669.80.
The formula for calculating the mark up percentage is as follows:
sticker price - invoice price/invoice price • 100 = percent mark up
<h3>How to find the percentage mark up?</h3>
Percentage mark up can be described as follows:
percentage mark up = selling price per unit - cost price per unit / cost price per unit × 100
Therefore,
Mark up is the difference between a product's selling price and cost as a percentage of the cost.
Therefore, the formula for calculating the mark up percentage is as follows:
sticker price - invoice price/invoice price • 100 = percent mark up

Let the oranges cost = x
Let the apples cost = y
According to given conditions, equation becomes:
.... (1)
.....(2)
Multiplying equation (1) by 8 and equation (2) by 12 to get y
96x+48y=43.04 .... (3)
96x+60y=44.16 .... (4)
Now subtracting both equations we get,
12y = 1.12
y = 0.093
Hence, cost of 1 apple = $0.093
As 12x+6y=5.38
12x+6(0.093)=5.38
12x=4.822
x = 0.40
Hence, cost of 1 orange = $0.40
A=l*w
A=0.35 km*0.3=0.05 km^2
we transform in meters
0.05 km^=50m^2
