Lawrence worked 8 hours each day on Monday, Tuesday and Friday. He worked 5.5 hours on both Wednesday and Thursday. How many hours would Lawrence work each day if he worked the same number of hours each day? Give the rationale and then the answer.
Let's think step by step. 8 hours * 3 = 24 hours. 5.5 * 2 = 11 hours. 24 + 11 = 35 hours. 35 / 7 = 5 hours. Lawrence would work 5 hours each of the 7 days in a week.. The answer is: 5.

Susan loves chairs. In her house there are red chairs, yellow chairs, and blue chairs. There are 5 red chairs. There are 4 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. How many chairs are there in Susan's house? Give the rationale and then the answer.
Let's think step by step. The number of yellow chairs is 5 chairs 4 = 20 chairs. The number of blue chairs is 20 chairs 2 chairs = 18 chairs. There are 5 chairs + 20 chairs + 18 chairs = 43 chairs in Susan's house.. The answer is: 43.

Andy and Bob went to the canteen to buy snacks. They spent the same amount. Andy bought a can of soda at $1 and two hamburgers at $2 each. Bob ordered two sandwiches for $3 and a can of fruit drink. How much did Bob's fruit drink cost? Give the rationale and then the answer.
Let's think step by step. Two hamburger cost 2 x $2 = $4. So, Andy spent $1 + $4 = $5. Therefore, Bob's fruit drink cost $5 - $3 = $2.. The answer is: 2.
