Question

Determine which situation could be represented by the system of linear inequalities given below

4x + 5y < 180
x + y > 40
On a math test, questions are worth either 4 or 5 points each. The test has 40 questions in all with a maximum score of 180 points.
B.
A grocery store sells oranges in 4-pound and 5-pound bags. The store sells no more than 180 pounds of oranges in a day, and they want to sell at least 40 bags of oranges each day.
C.
At a pharmacy, packs of generic cotton balls are sold for $4 each and packs of name brand cotton balls are sold for $5 each. At the start of a day, the pharmacy has 40 packs of cotton balls that will earn a minimum sales revenue of $180.
D.
A bookstore sells sets of notebooks which contain either 4 or 5 notebooks each. The owner wants to sell at least 40 sets of notebooks each day, which is a minimum of 180 notebooks.

Answer 1

Answer with explanation:

The two linear Inequality given below is:

1.→ 4 x + 5 y < 180

2.→x + y > 40

We have to express this inequality into a Situation.

→Representation of Option A in terms of equation

x=Question which has 4 points

y=Question which has 5 points

1. x +y =40

2. 4 x +5 y ≤ 180

→→→→Representation of Option B in terms of equation

x=Number of 4 pound bag

y=Number of 5 Pound bag

1. 4 x +5 y < 180

2. x +y > 40

→Representation of Option C in terms of equation

x=Number of cotton balls which are sold at $ 4

y=Number of cotton balls which are sold at $ 5

1. 4 x +5 y < 180

2. x +y > 40

3. 4 x < 180

4. 5 y <180

→Representation of Option D in terms of equation

x=Number of notebooks in a set of Notebooks which contain 4 notebook

y=Number of notebooks in a set of Notebooks which contain 5 notebook

1. 4 x +5 y < 180

2. x +y > 40

3. 4 x < 180

4. 5 y < 180

Option B ,is most Appropriate representation of the situation.

Answer 2

The answer is (B)

Explanation:

It would not be a, the maximum score is 180, so it would be less than or equal to.

It is (B), since they need to sell at least 40 bags a day, and max is 180.

Hope this helps!
