The National Honor Society is selling tickets for the spring dance. Tickets are $12 for couples and $8 for singles. Let x be the number of couples and y be the
number of singles. This system of equations represents the situation in which ticket sales totaled $1,580 and a total of 250 students attended the dance.
12x + 8y = 1,580
2x + y = 250
How many singles tickets were sold?
A)15
B)40
C)105
D)133​

Respuesta :

Answer:

40 single tickets were sold.

Step-by-step explanation:

12x+8y=1580

2x+y=250

------------------

y=250-2x

12x+8(250-2x)=1580

12x+2000-16x=1580

-4x+2000=1580

-4x=1580-2000

-4x=-420

4x=420

x=420/4=105

y=250-2(105)=250-210=40
