Answer :
0.75n=18.00
You see, you would have to see how many cups she sold and by doing that you have to divide .75 by 18.00 to represent that you put n with the .75 and that causes you to need to get n alone so you divide .75 from 18 and get your answer

You can convert the description to symbolic representation.
The equation that can express how many cups of lemonade Jatonia sold is [tex]0.75 \times n = 18[/tex] which results in [tex]n = 24[/tex]
How to make equations for expressing the given conditions?
Whatever the condition is given, try converting it into symbolic forms.
For example, if it is said that something is increased, then you do addition by putting + sign.
You can use such techniques to convert given descriptions to equations or mathematical expressions mostly.
How to form the equation for given condition?
Since one cup is sold for 0.75 price, thus n cups will be sold in n times 0.75 price (since 0.75 + 0.75 ... n times is same as 0.75 times n)
This fact can thus, be written as [tex]0.75 \times n[/tex]
The cost for n cups is 18, thus the cost we get is equal to 18.
Thus, we have: [tex]0.75 \times n = 18[/tex]
Since we need the expression for getting amount of cups(denoted by n), we will try to make n left alone in the left side.
Thus ,we will divide by 0.75 on both the sides.
Thus we get:
[tex]0.75 \times n = 18\\\\\dfrac{0.75 \times n}{0.75} = \dfrac{18}{0.75}\\\\n = 24[/tex]
Thus, the equation that can express how many cups of lemonade Jatonia sold is [tex]0.75 \times n = 18[/tex] which results in [tex]n = 24[/tex]
