Question: Mark wants to order a pair of slippers for his wife with her initials embroidered on top. The slippers are currently $50.00 and are 10% off. The embroidery will be $5.50 per shoe and shipping is a flat rate of $10.00. How much will the slippers cost?
Answer: Step-by-step reasoning process: The slippers are $50.00 and currently 10% off so that’s 50 * .10 = $5.00 discount. The slippers are $50.00 with a $5.00 discount which makes them 50 - 5 = $45.00. The embroidery will be $5.50 per shoe, and 2 shoes make a pair so it will cost 5.50 * 2 = $11.00. The shoes are on sale for $45.00, the embroidery will be $11.00 and the shipping is $10.00 for a total of 45 + 11 + 10 = $66.00.
So the answer is 66.

Question: Becky has 50 necklaces in her jewelry collection. 3 of the necklaces have broken beads so she collects the unbroken beads for crafting and throws the other parts of the 3 the necklaces out. Becky buys 5 new necklaces that week. She decides to give 15 of her old necklaces to her friends as gifts. How many necklaces does she own now?
Answer: Step-by-step reasoning process: Becky started with 50 necklaces and then got rid of 3, 50 - 3 = 47 necklaces. Becky buys 5 new necklaces that week, 47 + 5 = 52 necklaces. She gives 17 of her necklaces as gifts to friends, 52 - 15 = 37 necklaces Becky owns now.
So the answer is 37.

Question: Jimmy bought 3 pens for school for $1 each, 4 notebooks for $3 each and 2 folders for $5 each. If he paid with a $50 bill, how much change will he get back?
Answer:
Step-by-step reasoning process: Jimmy spent 3 * $1 = $3 on pens. He spent 4 * $3 = $12 on notebooks. He spent 2 * $5 = $10 on folders. He spent $3 + $12 + $10 = $25 in total. His change will be $50 - $25 = $25.
So the answer is 25.
