The dog toys Samantha buys for her dog are "buy one get one half off" and all cost $12.00 each. She buys 4 toys. How much does she spend on dog toys?
Let's think: If she buys 1 toy at $12.00 she gets the 2nd toy 1 / 2 off, the 2nd toy is 12 * .5 = $6.00. 1 full - priced toy is $12.00 and 1 / 2 priced toy is $6.00 so these 2 toys come to 12 + 6 = $18.00. She buys 2 more toys that are "buy one get one 1 / 2 off" so all total she spends 2 * 18 = $36.00.. The answer is: 36.

Johnny is buying planks of wood to build some tables. Each table needs a plank of wood for each of the legs and 5 planks of wood for the surface. If Johnny wants to build 5 tables, how many planks of wood does he need?
Let's think: Each table needs 1 plank of wood * 4 legs = 4 planks of wood for the legs. This means each table needs 4 planks of wood for legs + 5 planks of wood for the surface = 9 planks of wood. To build 5 tables, Johnny will therefore need 9 planks of wood * 5 tables = 45 planks of wood.. The answer is: 45.

Dante needs half as many cups of flour to bake his chocolate cake as he needs eggs. If he uses 60 eggs in his recipe, calculate the total number of cups of flour and eggs that he uses altogether.
Let's think: Dante needs half as many cups of flour to bake his chocolate cake as he needs eggs, meaning he needs 60 / 2 = 30 cups of flour for his recipe. Altogether, Dante needs 30 + 60 = 90 eggs and cups of flour for his recipe.. The answer is: 90.

When Jane visited Iran, she visited 6 more than twice as many rehabilitation centers as Han. Han visited 2 less than twice as many rehabilitation centers as Jude did. Jude visited half fewer rehabilitation centers as Lisa did. If Lisa visited 6 rehabilitation centers, how many rehabilitation centers did they all visit assuming they are all different?
Let's think:
Jude visited 1 / 2 * 6 = 3 rehabilitation centers. Han visited 2 * 3 - 2 = 4 rehabilitation centers. Jane visited 6 + 2 * 4 = 14 rehabilitation centers. They all visited 6 + 3 + 4 + 14 = 27 rehabilitation centers.. The answer is: 27.
