Tickets to the valentine dance cost $3 per person or $5 per couple.
$475 worth of tickets were sold and 180 people attended the dance.
write a system of equations to represent this problem. how many couple tickets were sold? how many individual tickets were sold?
you should have two equations. show your work.

Step-by-step explanation:

The two equations are for the revenue and the number of attendees.

  3p +5c = 475 . . . . . . revenue from ticket sales (dollars)

  p +2c = 180 . . . . . . . number of attendees (2 persons per couple)

Substituting (180-2c) for p in the first equation, we get ...

  3(180 -2c) +5c = 475

  540 -c = 475 . . . . . . . . . simplify

  540 -475 = c = 65 . . . . . add c-475

  p = 180 -2(65) = 50 . . . . find p from c

65 couple tickets and 50 individual tickets were sold.

i really dont know

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
