I need a clearer understanding of how to solve: Mica went to the grocery store and bought 2 kilograms of pasta that costs $1.5; 1/4 kilogram of ground beef costs $8 for 1 kilogram; two jars of pasta sauce costs $2 per jar. Mica also wants to buy a $6 Quesadilla for snacks.  How much money should she have with her to buy all those?
