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
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.
