Best Buy Project
Unit Rate Problem
Which is the best buy out of these packs of spoons?
*I set up the proportions for each pack. The # of spoons as the denominator and the price at the top.
*I set u the unit proportion with "1 spoon" as the denominator and left the numerator blank so you can solve for it later.
*I divided the price, by the # of spoons for each pack to get its unit rate. Whichever unit rate was the smallest would be the best buy.
Why is Unit Rate Helpful?
What's the Better Buy?
The 600 pack is the better buy because I solved for the unit rate to see how much each spoon would be. The less the unit rate is, the better and the 600 pack had the smallest unit rate so each spoon would be cheaper.
