Ticket Prices Two hundred tickets were sold for a

baseball game, which amounted to $840. Student

tickets cost $3, and adult tickets cost $5.

(a) Let x be the number of student tickets sold and y

be the number of adult tickets sold. Write a system

of linear equations whose solution gives the

number of each type of ticket sold.

(b) Use the method of substitution to solve the system.

x + y = 200

3 x + 5 y = 840

so

y = (200-x)

substitute (200-x) for y

3 x + 5 (200-x) = 840

3 x + 1000 - 5 x = 840

2 x = 160

x = 80

y = 120
