.For a hockey game, tickets are $220 for
Romashka [77]

Answer:

900 front row seats

Step-by-step explanation:

Tickets for front row seat = 220 dollars (y)

Cost of remaining seats ticket = 50 dollars (z)

Number of front row seats = x

Number of remaining seats = 2050 (w)

Total amount earned when stadium is full = 300,500 dollars (T)

so if we formulate this using our variables y,z,x,w and T problem it becomes:

y*x + z*w = T, which says the

Tickets for front row seat times Number of front row seats plus Cost of remaining seats ticket times Number of remaining seats gives us Total amount earned by the stadium.

220*x + 2050*50 = 300500

220*x = 300500-102500

220*x = 198000

divide both side by 220

x = 900
