The available parking area of a parking lot is 600 square meters. A car requires 6 square meters of space, and a bus requires 30 square meters of space. The attendent can handle no more than 60 vehicles.
(a) Let x represent the number of cars and let y represent the number of buses. Write a system of inequalities to represent the number of cars and buses that can be parked on the lot.
(b) If the parking fees are $2.50 for cars and $7.50 for buses, how many of each type of vehicle should the attendent accept to maximize income? What is the max. income?
I'm not sure if these equations are right for part (a)
6x+30y is less than or equal to 600
x+y is less than or equal to 60
x is greater than or equal to 0
y is greater than or equal to 0
Can someone check if these are right or not?
And what would my function befor the profit in terms of x and y?
f(x,y)=2.50x+7.50y
Once I know if the function and the equations are right i will be able to graph and solve. Any help is greatly appreciated.
And how do you do greater than/less than equal signs?
