Question: Samantha bought a crate of 30 eggs for $5. If she decides to sell each egg for 20 cents, how many eggs will she have left by the time she recovers her capital from the sales?
Answer: There are 100 cents in each $1 so $5 gives 5 * 100 cents = 500 cents. To recover her capital of 500 cents from a selling price of 20 cents per egg she has to sell 500 / 20 = 25 eggs. There were 30 eggs in the crate to start with so she will have 30 - 25 = 5 eggs left. The answer is 5.

Q: Kylie and Kayla pick apples together and take home 340 apples total. If Kayla picked 10 more than 4 times the amount of apples that Kylie picked, how many apples did Kayla pick?
A: Let x be the number of apples Kylie picked. Kayla picked 10 + 4x apples. 340 = x + (10 + 4x). 340 = 5x + 10. 330 = 5x. x = 66 apples. Kayla picked 10 + 4(66) = 274 apples. The answer is 274.
