A rental shop charges $12 per hour for mountain bikes and $8 per hour for road bikes. If a group rents 3 mountain bikes and 4 road bikes for $76, and another group rents 5 mountain bikes and 2 road bikes for $88, how much does it cost to rent each type of bike per hour?

• 3b + 4r = 76; 5b + 2r = 88
• 4b + 3r = 76; 3b + 5r = 88
• 2b + 4r = 76; 6b + 2r = 88
• 3b + 2r = 76; 5b + 4r = 88
