Tickets to a play cost $5 for adults and $2 for children. If 1,750 tickets were sold for a total of $7,100, how many children’s tickets were sold? Can someone explain me how to make this one step by step?

Respuesta :

a - quantity tickets  for  adults.  It costs 5a dollars
c - quantity tickets for children. It costs 2c dollars.

There were 1750 tickets sold, so  a+c=1750$.  That's mean  a = 1750 - c. 

Total: 7 100$,  That's mean  5a + 2c = 7 100.  Substitute now  1750-c instead "a" :

5(1750-c) + 2c = 7100
8750 - 5c + 2c = 7100
-3c = -1650    |divide (-3)
c = 550

So a =1750 -c = 1750 - 550 = 1200

There were sold 1200 tickets for adults and 550 tickets for children

The number of children's ticket sold for the play is 550.

What are the linear equations that represent the question?

5a + 2b = $7100 equation 1

a + b = 1750 equation 2

Where:

a = adult tickets sold

b = number of children's ticket sold

What is the number of children's ticket sold?

In order to determine the answer, multiply equation 2 by 5:

5a + 5b = 8750 equation 3

Subtract equation 3 from equation 1

3b = 1650

Divide both sides by 3

b = 550
