Question
Write the linear inequality in standard form for this situation: Ms. Savva is ordering pizzas and breadsticks for a school party and has a budget of no more than $81. An order of breadsticks costs $7 and a pizza costs $13.
- 7x + 13y < 81
- 7x + 13y ≤ 81
- 7x + 13y ≥ 81
- 7x + 13y > 81
Hint:
we have to write the linear inequality in standard form for this situation. Mrs Savva is ordering pizzas and breadsticks for school party and has no budget of more than $ 81. Breadsticks cost $7 and pizza costs $13. Make them as variable and write the equation.
The correct answer is: 7x + 13y ≤ 81
Here we have to write the linear inequality in standard form.
Firstly , the budget is no more than $81.
The breadstick cost is $7 and pizza cost is $13
Let breadstick be x and pizza be y , we can write,
7x + 13y ≤ 81 [ in inequality no more than symbol is ≤ ]
Therefore, the correct answer is 7x + 13y ≤ 81 .
or,
Let the number of breadsticks be x and the number of pizzas be y.
Since the budget is not more than $81, the inequality symbol will have “≤”.
The linear inequality is 7x + 13y ≤ 81
In this question, Here we have to write the standard form of linear inequality. Always remember in inequality no more than symbol is ≤. And make variable for that also.
