Bryan wants to buy candy and gum to sell at the concession stand during the volleyball game. Candy cost 1$ per pack and gum cost 0.75$ per pack. If he only had 75$ to spend

Answers

Answer:

The solution in the attached figure

Step-by-step explanation:

Let

x ----> the number of candy pack that Brian can buy

y ---> the number of gum pack that Brian can buy

we know that

The inequality that represent this situation is

$x+0.75y\leq 75$

The solution is the shaded area below the solid line $x+0.75y=75$

The slope of the solid line is negative

using a graphing tool

The solution is the shaded area

Remember that the value of x and the value of y cannot be a negative number

see the attached figure
