Carmela has $7 and each of her four cousins has $2. How much will Carmela have to give to each of her cousins so that she and her cousins will have the same amount of money? Give the rationale and then the answer.
Let's think step by step. Carmela's four cousins have a total of $2 x 4 = $8. The total money they all have is $7 + $8 = $15. There will be 1 (Carmela) + 4 (cousins) = 5 people who will be sharing equally the money. So each of them should get $15 / 5 = $3. Hence, Carmela has to give a total of $7 - $3 = $4 to her 4 cousins. Therefore, each of her cousins will get $4 / 4 = $1.. The answer is: 1.

Jonsey is awake for 2/3 of the day and spends 1/2 her time awake playing outside and the rest inside. Her brother, Riley, is awake for 3/4 of the day and spends 1/3 of his day outside and the rest inside. How much time, on average, do they spend inside? Give the rationale and then the answer.
Let's think step by step. Jonsey is awake for 16 hours because 24 x (2 / 3) = 16. Jonsey spends 1 / 2 her day inside because 1 - (1 / 2) = 1 / 2. Jonsey spend 8 hours inside because 16 x (1 / 2) = 8. Riley is awake for 18 hours because 24 x (3 / 4) = 18. Riley spends 2 / 3 of his day inside because 1 - (1 / 3) = 2 / 3. Riley spends 12 hours inside because 18 x (2 / 3) = 12. In total they spend 20 hours inside because 8 + 12 = 20. On average, they spend 10 hours inside because 20 / 2 = 10.. The answer is: 10.

Isabella earns $5 an hour babysitting. She babysits 5 hours every day, 6 afternoons a week. After babysitting for 7 weeks, how much money will Isabella have earned? Give the rationale and then the answer.
Let's think step by step. She earns 5 * 5 = $25 in a day. In a week she earns 25 * 6 = $150. In 7 weeks, she earns 150 * 7 = $1050.. The answer is: 1050.
