Question 1205800
she wants to have a maximum of 60 dollars in 1 dollar bills and 5 dollar bills.
x = number of 1 dollar bills.
y = number of 5 dollar bills.


the inequality is x + 5y <= 60


to graph this inequality using the desmos.com calculator, graph the opposite of the i equality.


the area on the graph that is not shaded is the region of feasibility.


the constraint inequalities are
x + 5y <= 60
x >= 0
y >= 0


x and y must be greater then or equal to 0 because negative dollar amounts are not allower.


the graph looks like this.

any point on the line or in the unshaded area is good.


the objective function is x + 5y <= 60.


any of the points shown meet that criteria.


for example, the point (45,3) makes x + 5y <= 60 equal to 45 + 15 = 60 which is less than or equal to 60.
