the members of the school orchestra agree to buy at least 250 tickets for an outside concert. They buy 20 fewer lawn tickets than balcony seats. What is the least number of balcony seats bought?

Respuesta :

Answer:

135 seats

Step-by-step explanation:

Let number of balcony seats = y

Let number of lawn seats = x

x+20=y                              --- (i)

x+y=250                            --- (ii)

Substituting for Y in (ii)

2x+20=250

x=115 seats (Lawn)

y= 135 seats (Balcony)
