Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
She'll be on vacation for 40 days and drinks 3 cups of coffee / pods per day for a total of 40 * 3 = 120 coffee pods. Her coffee pods come 30 in a box and she needs 120 coffee pods so that’s 120 / 30 = 4 boxes. Each box costs $8.00 and she needs 4 boxes so that’s 8 * 4 = $32.00. Final answer: 32.
