Walter buys a bus pass for $30. Every time he rides the bus, money is deducted from the value of the pass. He rode 12 times and $24 was deducted from the value of the pass. How much does each bus ride cost?
If Walter had $24 taken away for 12 bus rides, that means each bus ride cost him $2 — to find what one ride costs, divide 12 by 12 (=1). Then you must do the same to the cost: 24/12 = 2.
