Twenty people pre-bought plane tickets at a price of $155 per ticket. Thirty people bought their plane tickets at the gate and they each paid $200 for their ticket. How many more dollars did the people at the gate pay for their tickets than those passengers that pre-bought their tickets? Give the rationale and then the answer.
Let's think step by step. Pre - bought: 20 people * $155 = $3100. Gate bought: 30 people * $200 = $6000. $6000 - $3100 = $2900. The passengers that paid at the gate paid $2900 more dollars than those who pre - bought their tickets.. The answer is: 2900.

In a week, Rayman works out for half the number of hours Junior takes to work out. Wolverine, their friend, works out for twice the combined total number of hours both Rayman and Junior take during their workouts. Calculate the number of hours Wolverine takes doing her workouts if Rayman does workouts for 10 hours in a week. Give the rationale and then the answer.
Let's think step by step. If Rayman takes 10 hours doing his workouts, half the number of hours junior takes, then Junior takes 2 * 10 = 20 hours to do his workouts in a week. Altogether, Junior and Rayman take 20 + 10 = 30 hours doing their workouts in a week. Wolverine takes 2 * 30 = 60 hours to do her workouts in a week, twice the total number of hours Rayman and Junior takes.. The answer is: 60.

Emma bought a loaf of bread that had a certain number of slices. Her little cousin Andy ate 3 slices from the bread at two different points in time, and then Emma decided she would make toast with the remaining slices. If she uses 2 slices of bread to make 1 piece of toast bread, how many slices were in the original loaf if she was able to make 10 pieces of toast bread and had 1 slice of bread left? Give the rationale and then the answer.

Let's think step by step. Little Andy ate 3 slices 2 times giving a total of 3 * 2 = 6 slices of bread. 1 piece of toast bread requires 2 slices of bread so 10 pieces need 10 * 2 = 20 slices of bread. There is 1 slice of bread left so in total there were 6 + 20 + 1 = 27 slices of bread in the loaf.. The answer is: 27.
