How much did the lectures cost per hour? $7.33 O $7.75 O $9.00 O $9.75 O $12.00

Explanation / Answer

Let per lecture costs $x, per workshop costs $y and per examination costs $z.

According to first c ondition

per hour examination costs = 2 x per hour workshop cost

or z=2y

and also per hour workshop cost = 2 x per hour lecture cost

i.e. y= 2x

so total cost in all modes of all hours

so $12x+ $24y+$3z = $528

or 12x + 48x + 6y = 528

or 12x + 48x + 12y = 528

or 72x = 528

or x= 528/72 = 7.33

So required cost is $7.33 per lecture or first option is correct answer.
