Answer: She paid 3 x $15 = $45 for the makeup palettes. She paid 4 x $2.50 = $10 for the lipsticks. She also paid 3 x $4 = $12 for the boxes of hair color. Therefore, Maddie paid a total of $45 + $10 + $12 = $67 for the beauty products. The answer is 67.

Question: Laticia knitted 4 pairs of socks for her nephew. She did such a good job that everyone asked her to start selling them. In the first week, she knitted 12 pairs of socks. In the second week, she knitted 4 more pairs than the week before. On the third week, she only knitted half of the total of the first two weeks. In the fourth week, she knitted 3 fewer pairs than the week before. How many pairs of socks did Laticia knit altogether?
Answer: In the second week, she knitted 12 + 4 = 16 pairs of socks. In the first two weeks, she knitted 12 + 16 = 28 pairs of socks. On the third week, she knitted 28 / 2 = 14 pairs of socks. On the fourth week, she knitted 14 - 3 = 11 pairs of socks. Altogether, Laticia knitted 4 + 12 + 16 + 14 + 11 = 57 pairs of socks. The answer is 57.

Question: The average speed for an hour drive is 66 miles per hour. If Felix wanted to drive twice as fast for 4 hours, how many miles will he cover?
Answer: If Felix drives twice as fast, he will be covering 2 * 66 = 132 miles per hour. In four hours, driving at 132 miles per hour, since distance = speed * time, Felix will cover 132 * 4 = 528 miles. The answer is 528.

Question: Marcia's hair is 24" long at the beginning of the school year. She cuts half of her hair off and lets it grow out 4 more inches. She then cuts off another 2" of hair. How long is her hair?
Answer:
Her hair was 24" long and she cut half off so she cut 24 / 2 = 12 inches. Her hair was 24" long and she cut 12" off so she has 24 - 12 = 12 inches left. She has 12" of hair and lets it grow 4 more inches for a total of 12 + 4 = 16 inches. She has 16" and cuts off 2 more inches which leaves her hair 16 - 2 = 14 inches long. The answer is 14.
