Jen butler has been pricing speed-pass train fares for a round trip to New York three adults and four children must pay $118 two
adults and three children must pay 84$ find the price of the adults ticket and the price of a child’s ticket
1 answer:
Answer:
Adult’s ticket = $ 18
Child’s ticket = $ 16
Step-by-step explanation:
Adults: x
Children: y
(3x + 4y = 118) * (2) = 6x + 8y = 236
(2x + 3y = 84) * (-3) = -6x - 9y = -252
Add both equations:
-y = - 16
y = 16
3x + 4(16) = 118
3X + 64 = 118
3X = 118 - 64
X = 54/3=18
