A company that manufactures cell phones first pays a start-up cost, and then spends a certain amount of money to manufacture each cell phone. If the cost of manufacturing c cell phones is given by the equation y = 275c + 125, then the value 275 represents

• the start-up cost

• the profit earned from the sale of one cell phone

• the amount spent to manufacture each cell phone

• the average number of cell phones manufactured

• y = 125x + 15

• y = 15x + 125

• y = 125x - 15

• y = 125 - 15x
