[Question]: Vicente saw Sophie's mom giving Sophie 20 oranges every day to carry to school to eat. He also saw Hannah's dad giving Hannah 40 grapes every day to eat at the school. If he counted the number of fruits that the girls were given for 30 days, calculate the total number of fruits that Sophie and Hannah had eaten in the 30 days.
[Answer]: If Sophie was given 20 oranges every day for thirty days, she had taken 20 * 30 = 600 oranges to school. Similarly, in the thirty days, Hannah had taken 40 * 30 = 1200 grapes to school. In the thirty days, Hannah and Sophie took 1200 + 600 = 1800 fruits to school.
So the answer is 1800.

[Question]: Tim has to go to the doctor for a sporting injury. He gets an MRI which costs $1200. The doctor needs to examine it for 30 minutes and charges $300 per hour. There is also a $150 fee just for being seen. Insurance covered 80% how much did he pay?
[Answer]: The doctor charged 300 / 2 = $150. So the total cost was 150 + 150 + 1200 = $1500. The insurance covered 1500 * .8 = $1200. So he paid 1500 - 1200 = $300.
So the answer is 300.

[Question]: Anna puts three slices of ham in each sandwich. If she has 31 slices of ham, how many more slices of ham does she need to make 50 ham sandwiches?
