[Question]Keanu was surfing towards the shore at a speed of 20 miles per hour. A shark was swimming alongside him, riding the same wave, when it doubled its speed and moved away from Keanu. There was a pilot fish swimming alongside Keanu and the shark, and when the shark increased its speed, the pilot fish also increased its speed and moved away from Keanu, but only increasing its speed by half as much as the shark had increased its speed by. What speed, in miles per hour, was the pilot fish swimming when it moved away from Keanu?
[Answer]The shark went from 20 miles per hour to a speed of 2 * 20 = 40 miles per hour. The shark increased its speed by 40 - 20 = 20 miles per hour. Half of the shark's increase in speed is 20 / 2 = 10 miles per hour. Thus the pilot fish had increased its speed to 20 + 10 = 30 miles per hour. The answer is 30.
Q: Every Sunday, Sean picks up 1 almond croissant and 1 salami and cheese croissant that are $4.50 each. He also grabs a plain croissant for $3.00 and a loaf of focaccia for $4.00. On his way home he stops and picks up 2 lattes for $2.50 each. How much did he spend?
A: The almond croissant and the salami and cheese croissant are $4.50 each so that's 2 * 4.50 = $9.00. He buys 2 lattes that are $2.50 each so that's 2 * 2.50 = $5.00. The flavored croissants are $9.00, the lattes are $5.00 and he also grabbed a plain croissant for $3.00 and focaccia for $4.00 for a total of 9 + 5 + 3 + 4 = $21.00. The answer is 21.

[Question]School coaches bought sports equipment. Coach A bought ten new basketballs for $29 each, while coach B bought 14 new baseballs for $2.50 each and a baseball bat for $18. How much more did coach A spend than coach B?
[Answer]Coach A spent $29x 10 = $290 for the 10 basketballs. Coach B spent $2.50x14 = $35 for the 14 baseballs. So, Coach B spent a total of $35 + $18 = $53 for the baseballs and a bat. Thus, Coach A spent $290 - $53 = $237 more than coach B. The answer is 237.
