For level 3 course, examination hours cost twice as much as workshop hours and workshop hours cost twice as much as the lecture hours. How much did lecture cost per hour

Respuesta :

how much does the workshop cost

Answer:

Step-by-step explanation:

Let the cost of examination is = $x

Let the cost of  workshop hours is = $y

and Let the cost of lecture hours = $z

Now as it has been given that examination hours cost twice as much as workshops hours then

x = 2y -----(1)

Workshop hours cost twice as much as the lecture cost.

y = 2z ----(2)

Then we replace the value of y = [tex]\frac{x}{2}[/tex] from equation (1) to (2)

[tex]\frac{x}{2}[/tex] = 2z

x = 4z

Therefore, lecture cost is 4 times more than the cost of examination.
