The ace novelty company wishes to produce two types of souvenirs: type A and type B.

To manufacture:

Type A requires: 2 minutes on machine 1 and 1 minute on machine 2

Type B requires: 1 minute on machine 1 and 3 minutes on machine 2

There are 180 minutes available on machine 1 and 300 minutes available on machine 2 for processing the order.

Let x = # of type A produced

Let y = # of type B produced

a. Write linear equalities that give appropriate restrictions on x and y

b. if each type a souvenir will result in a profit of $1 and each type b souvenir will result a profit of 1.20 then express the profit, p in terms of x and y.

c. algebraically determine how many souvenirs of each type the ace novelty company should produce so as to maximize profit

Let x be the number of Type A souvenirs, and let y be the number of Type B souvenirs to be made. Then the profit in dollars will be P = x + 1.2y, which is the objective function to be maximized.

Next, we need to set up the constraints. On Machine I, there are at most 180 minutes available, and each Type A souvenir uses 2 minutes and each Type B souvenir uses 1 minutes.

So the total amount of time on Machine I is given by 2x+y and cannot be greater than 180 minutes, so 2x+y ≤ 180 is our first constraint. Similarly for Machine II, the amount of time is x + 3y and cannot exceed 300 minutes, so x + 3y ≤ 300 is our second constraint.

Lastly, we cannot make negative numbers of souvenirs, so x ≥ 0 and y ≥ 0 are also constraints. In total, we need to maximize P = x + 1.2y subject to the constraints

2x + y ≤ 180

x + 3y ≤ 300

x ≥ 0, y ≥ 0
