Question

Jen Butler has been pricing Speed-Pass train fares for a group trip to New York. Three adults and four children must

pay $129. Two adults and three children must pay $92. Find the price of the adult's ticket and the price of a child's
ticket. Find the price of the child and adult ticket

Answer 1

Adult:19

Child:18

Explanation:

Adults: x

Children:y

Equation 1: 3x+4y=129

Equation: 2x+3y=92

Let's now graph our equations on the desmos graphing calculator!!!

Look for the points that meet each other on the graph which is (19,18)

So $19 for an adult and $18 for children
