Answer: 25y= 60x
190x +25y= 37500
Step-by-step explanation:
Let x = Number of balcony tickets.
then, Number of lower level tickets = 5x
Let y = Number of mezzanine tickets
Money made from ,
balcony tickets = 15x
lower level tickets = 35 (5x) = 175 x
mezzanine tickets = 25y
Money made from mezzanine tickets= 4 x( money made from balcony tickets.)
⇒ 25y = 4 (15x)
⇒ 25y= 60x (i)
Also, total cost of the tickets = 15x+175x+25y = 37500
⇒ 190x +25y= 37500 (ii)
From (i) and (ii), the system of linear equations could be used to solve for the number of each type of ticket sold:
25y= 60x
190x +25y= 37500
