Question: For a New Year’s Eve appetizer, Alex is serving caviar with potato chips and creme fraiche. He buys 3 individual bags of potato chips for $1.00 each and dollops each chip with some creme fraiche that costs $5.00 and then the $73.00 caviar. This appetizer will serve 3 people. How much will this appetizer cost per person?
Answer: He buys 3 bags of potato chips for $1.00 each so that’s 3 * 1 = $3.00. The chips are $3.00, the creme fraiche is $5.00 and the caviar is $73.00 for a total of 3 + 5 + 73 = $81.00. The appetizer costs $81.00 and will serve 3 people so it will cost 81 / 3 = $27.00 per person. The answer is 27.

Question: Jerry works five days a week as a waiter and earns a variable amount of tips every night. The past four nights, he earned $20, $60, $15, and $40. How much does he need to earn tonight if he wants to make an average of $50 in tips per night?
Answer: The total money Jerry needs to make for 5 days to get $50 per night is 5 nights * $50 / night = $250. His total earnings for the past four days is $20 + $60 + $15 + $40 = $135. So, Jerry needs to earn $250 - $135 = $115 in tips tonight. The answer is 115.

Question: Rebecca runs a hair salon. She charges $30 for haircuts, $40 for perms, and $60 for dye jobs, but she has to buy a box of hair dye for $10 to dye every head of hair. Today, she has four haircuts, one perm, and two dye jobs scheduled. If she makes $50 in tips, how much money will she have in dollars at the end of the day?
Answer:
Rebecca will make 30 * 4 = $120 from haircuts today. She will make 60 * 2 = $120 from dye jobs. She will spend 10 * 2 = $20 on hair dye. With the $40 perm and tips, at the end of the day, Rebecca will have 120 + 120 + 40 - 20 + 50 = $310. The answer is 310.
