The expression shows that increasing a quantity by 20% is the same as multiplying the quantity by 1.2.

Part E
Suppose that Patricia drinks one-fourth of the lemonade in her glass. Write an expression in terms of p that represents the number of ounces Patricia drank.

If p represents the total number of ounces of lemonade in Patricia's glass, then the number of ounces she drank is one-fourth of p. Therefore, the expression is:

1/4p

To find the number of ounces Patricia drank, we need to determine one-fourth of the total amount of lemonade in her glass.

Let's assume the total amount of lemonade in her glass is represented by "p" ounces.

To calculate one-fourth of p, we divide p by 4.

Therefore, the expression that represents the number of ounces Patricia drank is:

(1/4) * p.

Simplifying the expression:

(1/4) * p = p/4.
