Hello. Need help with this practice question.

3. Use the Simplex Algorithm to solve the following:
I intend to set up a car rental fleet containing small and large cars. I will purchase my cars
in packages from three different motor retail outlets: MR1, MR2, and MR3. MR1's packages
each contains 40 small cars and 5 large cars; MR2's packages each contains 20 small cars and
5 large cars; MR3's packages each contains 10 small cars and 10 large cars.
I want my purchases to satisfy the following conditions:
• I should purchase no more than 40 packages altogether.
• The number of packages that I purchase from MR1 and MR2 combined should be at most
a third of the number of packages that I purchase altogether;
• I should purchase at most 300 large cars altogether; and
• The number of small cars that I purchase from MR2 and MR3 combined should be at
least 180 more than the number of small cars that I purchase from MR1.
How many packages should I purchase from each retail outlet in order to maximize the total
number of large cars in my fleet?
