Step-by-step reasoning process: Larry's shoulder height is 20% less than 5 feet, or 0.2 * 5 = 1 foot less than 5 feet. One foot less than 5 feet is 5 - 1 = 4 feet. If Barry stands on Larry's shoulders, they can reach 4 + 5 = 9 feet.
The question and answer:
Question and answer: Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples. Barry can reach apples that are 5 feet high. Larry is 5 feet tall, but his shoulder height is 20% less than his full height. If Barry stands on Larry's shoulders, how high can they reach?
The answer is 9

Step-by-step reasoning process: Hannah's earnings from the cookies is 40 x $0.8 = $32. Her earnings from the cupcakes is 30 x $2 = $60. Her total earnings for the cupcakes and cookies is $32 + $60 = $92. The cost of 2 sets of measuring spoons is 2 x $6.5 = $13. So, Hannah has $92 - $13 = $79.
The question and answer:
Question and answer: Hannah sold 40 pieces of cookies for $0.8 each and 30 cupcakes for $2 each. She used the money to buy 2 sets of measuring spoons for $6.5 each. How much money does she have left?
