Dwayne is selling hamburgers and cheeseburgers. he has 100 burger buns. each hamburger sells for $3, and each cheeseburger sells for $3.50. which system of inequalities represents the number of hamburgers, h, and the number of cheeseburgers, c, he must sell to have sales of at least $80?
h + c ≤ 80 3h + 3.5c ≤ 100
h + c ≤ 80 3h + 3.5c ≥ 100
h + c ≤ 100 3h + 3.5c ≤ 80
h + c ≤ 100 3h + 3.5c ≥ 80

Option D is correct.

The system of inequalities are:

;

Step-by-step explanation:

Let h represents the number of hamburgers and c represents the number of cheeseburgers.

From the given statement:

Each hamburgers sells for $3 each

then,

the total sales of hamburgers sells is 3h

Each cheeseburgers sells for $3.50 each

then,

the total sales of cheeseburgers sells is 3.50c

Since, he has 100 burgers

then the inequality :

And also, he must sell to have sales of at least $ 80

at least represented by symbol  

then the inequality is;

Therefore, the system of inequality:

;
