Answer:
p = 8
Step-by-step explanation:
well all you have to do is divide 72 by 9 which you get 8
so you can buy 8 pizzas.
The required inequality is 9p ≤ 72.
What are inequalities?
Inequalities are relations between two unequal quantities.
They are of four types:
- Greater than a > b: This says that a is greater than b in value.
- Less than a < b: This says that a is less than b in value.
- Greater than or equal to a ≥ b: This says that a is either greater than, or equal to b in value.
- Less than or equal to a ≤ b: This says that a is either less than, or equal to b in value.
How to solve the question?
In the question, we are informed that we are buying pizzas for a neighborhood party each pizza costs $9. We have $72 at most to spend on pizza.
We are asked to write an inequality to represent the situation by taking p as the variable showing the number of pizzas we can purchase.
The cost of one pizza = $9.
The number of pizzas we purchase = p.
Therefore, our total cost function = $9p.
Our total budget at max = $72.
We know that the total cost function cannot exceed the budget, that is, it is either less than, or equal to the budget. This can be shown as inequality:
Total Cost function ≤ Budget,
or, 9p ≤ 72.
Thus, the required inequality is 9p ≤ 72.
