Question: To celebrate a recent promotion, Arthur decided to treat himself to dinner at a nice restaurant. He ordered a nice appetizer for $8, a delicious ribeye steak for his entree at $20, had two glasses of nice red wine with dinner for $3 each, and a slice of caramel cheesecake for dessert for $6. He used a voucher for half off the price of his entree, but he very thoughtfully tipped his waitress a full 20% of what the full cost of his meal would have been without the discount. How much, including the tip, did Arthur spend on dinner?
Answer with step-by-step thinking: The cost of his food, before the voucher, was $8 + $20 + $3 + $3 + $6 = $40. The tip was $40 * .20 = $8. The voucher saved him $20 / 2 = $10. So the full price of Arthur's meal, with tip, was $40 - $10 + 8 = $38.
So the answer is 38.

Question: Christopher uses 1 packet of a sugar substitute in his coffee. He has 2 coffees a day. The packets come 30 to a box and cost $4.00 a box. How much will it cost him to have enough sugar substitutes to last him 90 days?
Answer with step-by-step thinking:
He uses 1 packet per cup of coffee and he has 2 cups a day so that's 1 * 2 = 2 packets. He wants enough to last him 90 days and he uses 2 packets a day so that's 90 * 2 = 180 packets. The packets come 30 to a box and he needs 180 packets so that's 180 / 30 = 6 boxes of sugar substitute. Each box costs $4.00 and he needs 6 boxes so that's 4 * 6 = $24.00.
So the answer is 24.
