Problem situation: Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade
. How many cups, x, will Bernie need to sell to make a profit of at least $20? Inequality that represents this situation: 20≤1.50x−6.50 Drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.

<em>Incomplete question: Missing Attachment</em>
<em>I will answer your question with the attached histogram</em>
<em></em>
Required
Determine the number of tall buildings that had more than 60 floors
The histogram can be interpreted as follows:
More than 60 floors is represented with the following group: 61 - 80
The frequency of group 61 - 80 is 10
<em>Hence, 10 buildings had more than 60 floors</em>
<h2>Answer:</h2>
We will use substitution to solve this system for x.
Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.
We now have our solution.
D.
We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.
Since the equation checks out, our solution is correct.
Here's what I did and I checked it So it is correct!!
