Northern Virginia Community College Ratios and Proportions Discussion
- February 04, 2022/ Homework Tutors
We use ratios and proportions every day in our lives and especially when shopping to determine the best deal for an item we want to buy.
For example, which deal is the best: 2 liters of milk for $3.80, or 1.5 liters of milk for $2.70?
In this case the “Unit” is 1 liter, and the Unit Prices are:
$3.80 / 2 liters = $1.90 per liter
$2.70 / 1.5 liters = $1.80 per liter
So the lowest Unit Price (and the best bargain) is 1.5 liters at $2.70.
Create your own problem based on an item that you bought in the last 2 weeks to show how you chose the best deal. Explain the steps detailing how you reached your decision.
