All total she found 2.50 + .30 + .15 + .05 = $3.00 in change.

Answer this question:Sharon’s vacation rental has a Keurig coffee machine. She will be there for 40 days. She has 3 cups of coffee (3 coffee pods) every morning. Her coffee pods come 30 pods to a box for $8.00. How much will she spend on coffee to last her for the entire vacation?
