Answer this question:Yvonne brings a box of chocolates to school. Half have nuts and half do not. The students eat 80% of the ones with nuts and eat half of the ones without nuts. If there are 28 chocolates left, how many chocolates were in the box?
The ones with nuts that they ate was 40% of the box because 80% x .5 = 40%. The ones without nuts that they ate equaled 25% of the box because 50% x .5 = 25%. They ate 65% of the box because 40 + 25 = 65. They left 35% of the box because 100 - 65 = 35. The box had 80 chocolates because 28 / .35 = 80.
The answer is 80.

Answer this question:Jaco wants to buy Christmas gifts for his 8 friends that are worth $9 each. Also, he wants to buy gifts for his mother and father that are of the same amount. He has a $100 budget to buy all gifts. How much is Jaco's budget for each of his mother and father's gift?
Jaco will spend a total of $9 x 8 = $72 for his 8 friends' gifts. He will be left with $100 - $72 = $28 for his mother and father's gift. So, Jaco's budget for each of his mother and father's gift is $28 / 2 = $14.
The answer is 14.

Answer this question:A spaceship is traveling to another planet. The spaceship travels at a consistent speed its entire journey unless it is stopped for the crew's break. After launch, the spaceship traveled for 10 hours then stopped for 3 hours. It then traveled for another 10 hours then stopped for 1 hour. After this, the spaceship would take an hour's break after every 11 hours of traveling and maintained this routine until the end of its journey. If the entire journey took 3 days then how long, in hours, was the spaceship not moving?
On the first day, the spaceship spent a total of 10 hours + 10 hours = 20 hours traveling. On the first day, the spaceship spent a total of 3 hours + 1 hour = 4 hours not moving. This is a total of 20 hours traveling + 4 hours not moving = 24 hours or 1 day. So the rest of the journey took place over 3 days journey 1 first day = 2 days. This is the same as 2 days * 24 hours = 48 hours. In these 2 days, the spaceship's time is split into 11 hours traveling + 1 hour break = 12 hour blocks. So in the last 2 days, the spaceship wasn't moving for a total of 48 hours / 12 hour blocks = 4 hours. Adding this to breaks from the first day shows that the spaceship was not moving for a total of 4 + 4 = 8 hours.
The answer is 8.
