Anvisha [2.4K]

Answer: 59 feet

cupoosta [38]

Answer:

There are 230 seats in the auditorium

Row 51 contains 203 seats.

Step-by-step explanation:

Equation: y = 3x + 50

3x is the rate at which the seats are and 50 is the the starting point.

y = 3(51) + 50

y = 203

Row 51 contains 203 seats.

y = 3(60) + 50

y = 180 + 50

y = 230

There are 230 seats in the auditorium
