One week you spent $24 on 6 subway tickets and 4 express bus tickets. the next week you spent $27 on 3 subway tickets and 7 express bus tickets. how much will it cost you to buy 5 subway tickets and 2 express bus tickets this week?

2 Subway Tickets and 3 Express Bus Tickets

To solve this problem, you first need to write the following 2 equations.
6x + 4y = 24
3x + 7y = 27
Where x is the number of subway tickets and y is the number of bus tickets.

Now, you just have to solve the system of equations. You can use substitution, elimination or graphing. The easiest is graphing. There are online graphing calculators that will graph the points and you just need to find the point of intersection.

The answer would be 13.5 minutes.
