Question

Patricia and her brother Ian help themselves to a pitcher of lemonade on the kitchen counter. Patricia takes a glass and fills it with p ounces of lemonade. Ian takes a bigger glass and pours himself 20% more lemonade than Patricia poured in her glass. Write an expression to represent the quantity of lemonade (in ounces) in Ian’s glass in terms of the quantity in Patricia’s glass (p).

Answer 1

The quantity of lemonade in Ian's glass can be represented as p + (0.20 * p) or p * (1 + 0.20) in terms of the quantity in Patricia's glass.

Step-by-step explanation:

To represent the quantity of lemonade in Ian's glass in terms of the quantity in Patricia's glass, we need to add 20% more lemonade to Patricia's amount. This means that Ian's glass will contain the quantity in Patricia's glass plus 20% of that quantity. In terms of the given quantity p, the expression for Ian's glass can be written as: p + (0.20 * p) or p * (1 + 0.20).
