Jenny Salinas · Answer 1

To answer the question, let x be the number of unlimited-ride pass for $50 and y be the number of entrance-only pass for $20. The following equations are useful to answer the question above,

x + y = 282

50x + 20y = 10,680

Solving for the variables above gives x = 168 and y = 114.

Therefore, there are 168 unlimited-ride passes that were sold.

Dalia Mullen · Answer 2

see you know that there were 282

passes sold right so the equation is x+y=282

where x and y are the respective types of tickets sold

now x+y=282

hence y=282-x

now see the amount collect is $10680

that is = >50x+20y=10680 ...

try to think a lil' here now substitute that equation which i gave you in the previous comment and viola ... you get x to be 168
