Unit 3/5 Fraction/Decimal Operations with Ratios and Rates
Everyone must go to the grocery store to buy food and supplies that keep our families healthy. Each family has a budget that they must stay within when shopping for these items.
Your group is planning a dinner for a few families of our community.
Your Math Challenge for this project is to find the ingredients needed at three different markets and compare the cost. We need to find the best deals so that we can create affordable meals to serve in a formal setting. We have a very strict budget and cannot spend more than allowed.
