Final answer:
The number of coach tickets purchased is 44. The number of sleeper car tickets purchased is 48.
Step-by-step explanation:
Let's solve the problem using a system of equations. Let x be the number of regular coach tickets purchased and y be the number of sleeper car tickets purchased.
From the given information, we can set up the following system of equations:
x + y = 92 (equation 1)
120x + 293y = 19,344 (equation 2)
Multiply equation 1 by 120 to eliminate x:
120x + 120y = 11,040 (equation 3)
Now, subtract equation 3 from equation 2:
120x + 293y - (120x + 120y) = 19,344 - 11,040
173y = 8,304
y = 48
Substitute the value of y into equation 1 to find x:
x + 48 = 92
x = 44
Therefore, the number of coach tickets purchased is 44 and the number of sleeper car tickets purchased is 48.
