Answer:
The minimum number of cups she must sell to reach her goal=43 cups
Step-by-step explanation:
Total earnings=Total Lemonade sales-Supplies expenditure
where;
Total earnings=$40
Total Lemonade sales=Price per cup×Number of cups sold(n)=(0.7×n)=0.7n
Supplies Expenditure=0.23 per cup=(0.23×n)=0.23n
Replacing;
40=0.7n+0.23n
Inequality; 0.7n+0.23n=40
Solving;
0.93n=40
n=40/0.93)=43 cups
The minimum number of cups she must sell to reach her goal=n=43 cups

To solve this problem you must apply the proccedure shown below:
1. You must apply the Pythagorean Theorem, which is:
a²=b²+c²
a is the hypotenuse and b and c the legs of the triangle.
2. You have that:
b=c=x
3. Therefore:
a²=2x²
(2√6)=2x²
4. Now, you must clear the x, as below:
x²/2=24
x²=24/2
x²=12
x=√12
x=2√3
5. Therefore, as you can see, the answer is 2√3
