Question

Jacob's family bought 4 adult tickets and 2 student tickets to the school play for $67. Tatianna's family

bought 3 adult tickets and 3 student tickets for $63. How much does each type of ticket cost?

Answer 1

ticket for adults is 12,5$

ticket for students is 8,5$

Explanation:

A is for adult tickets

S is for student tickets

4A + 2S = 67 /×3

3A + 3S = 63 /×(-2)

⇒ We multiply this

12A + 6S = 201

-6A - 6S = -126

⇒ Addition of both

6A = 75

A = 12,5$

and from 4A + 2S = 67 we have that S is 8,5$
