3. The area of a parking lot is 600 square meters. A car requires 6 square meter and a bus requires 30 square meters. The attendant can handle no more than 60 vehicles. If a car is charged \( \$ 10 \) to park and a bus is charged \( \$ 17 \) to park, how many of each type of vehicle should be accepted into the parking lot to maximize income? What will the maximum income be? Let \( x \) represent the number of cars accepted and y represent the number of busses. Use the inequalities \( x \geq 0, y \geq 0, x+y \leq 60 \), and \( 6 x+30 y \leq 600 \) and the related function \( f(x, y)=10 x+17 y \). (Hint: Count by 10 on each axis)
