You work two jobs. You earn $14.50 per hour as a salesperson and $11.60 per hour stocking shelves. Your combined earnings this month are $116.00. Let x represent the number of hours worked stocking shelves and let y represent the number of hours worked in sales. Graph the equation that models this situation. A bathtub is draining at a constant rate. After 1 minute, it holds 32 gallons of water. Four minutes later, it holds 16 gallons of water. Write an equation that represents the number y of gallons of water in the tub after x minutes.
