Math Problem Statement
Tasty Yogurt Manufacturing Co. makes 10 cents per container of plain yogurt that it sells and 12 cents per container of vanilla yogurt. They want to make a monthly profit of at least $3,200. This month, Tasty expects to sell at least 12,000 cups of plain yogurt (p), but no more than 15,000 cups of vanilla yogurt (v).
Part A:
Which of the following inequalities represent this situation? Select all that apply.
A. 10p +12v ≥ 3200
B. 0.10p + 0.12v ≥ 3200
C. p ≥ 12,000
D. p ≤ 12,000
E. v ≥15,000
F. v ≤ 15,000
Solution
To solve this problem, we need to translate the information given into mathematical inequalities that represent the situation. Let's go through each part step by step.
1. Profit Condition
Tasty Yogurt Manufacturing Co. wants to make a monthly profit of at least $3,200. The profit per container is:
- 10 cents per container of plain yogurt (which is in dollars)
- 12 cents per container of vanilla yogurt (which is in dollars)
The total profit is given by:
Since they want the total profit to be at least $3,200, the inequality is:
This inequality is represented by Option B.
Note: Option A is incorrect because it uses 10 and 12 instead of 0.10 and 0.12, which would result in a much higher required profit than intended.
2. Plain Yogurt Sales
Tasty expects to sell at least 12,000 cups of plain yogurt. This can be written as:
This inequality is represented by Option C.
Note: Option D is incorrect because it suggests , which contradicts the problem statement.
3. Vanilla Yogurt Sales
Tasty expects to sell no more than 15,000 cups of vanilla yogurt. This can be written as:
This inequality is represented by Option F.
Note: Option E is incorrect because it suggests , which contradicts the problem statement.
Conclusion
The correct inequalities that represent the situation are:
- B.
- C.
- F.
Would you like more details or have any questions?
Here are five related questions for further practice:
- If Tasty sells exactly 15,000 cups of vanilla yogurt, how many plain yogurt cups must they sell to meet the $3,200 profit goal?
- What is the minimum number of vanilla yogurt cups needed if Tasty sells exactly 12,000 plain yogurt cups?
- How would the inequalities change if the profit target was increased to $4,000?
- If Tasty sells 13,000 plain yogurt cups and 14,000 vanilla yogurt cups, what will be their total profit?
- How does the maximum number of vanilla yogurt cups affect the minimum number of plain yogurt cups required to meet the profit goal?
Tip: Always convert units correctly when dealing with profit calculations to avoid errors in inequalities and equations.
