[Question]Linda is painting her bedroom. Her bedroom has 4 walls, with the room being 20 feet wide by 20 feet long by 8 feet tall. One wall has a 3-foot by 7-foot doorway. A second wall has a 6-foot by 4-foot window. A third wall has a 5-foot by 7-foot doorway to a walk-in-closet. And the fourth wall is completely solid. What is the total area of wall space that Linda will have to paint?
[Answer]The solid wall is 8 ft. * 20 ft. = 160 sq. ft. The doorway is 3 ft. * 7 ft. = 21 sq. ft. The window is 6 ft. * 4 ft. = 24 sq. ft. The closet door is 5 ft. * 7 ft. = 35 sq. ft. The total area of the doors and windows is 21 sq. ft + 24 sq. ft. + 35 sq. ft. = 80 sq. ft. The solid wall is 160 sq. ft., so before the areas of the doors and window are taken into account, the total wall area is 4 * 160 sq. ft. = 640 sq. ft. Taking into account the doors and window, the total wall area Linda will have to paint is 640 sq. ft. - 80 sq. ft. = 560 sq. ft. The answer is 560.
Q: Grace baked 4 whole pumpkin pies. She sold 1 whole pumpkin pie and gave 1 whole pumpkin pie to her friend. The remaining whole pumpkin pies were each sliced into 6 pieces. Her family ate 2/3 pieces. How many pieces of pumpkin pie were left?
A: Grace sold and gave a total of 1 + 1 = 2 whole pumpkin pie. Her family was left with 4 - 2 = 2 whole pumpkin pie. There were a total of 2 x 6 = 12 pieces made from the 2 whole pumpkin pie. Her family ate 12 x 2 / 3 = 8 pieces. Therefore, 12 - 8 = 4 pieces of pumpkin pie were left. The answer is 4.
Question: The sum of the three sides of a triangle is 50. The right side of the triangle is 2 cm longer than the left side. Find the value of the triangle base if the left side has a value of 12 cm.
Answer: If the left side of the triangle is 12, and the right side is 2 cm longer, the right side is 12 + 2 = 14 cm long. The sum of the left and right sides of the triangle is 14 + 12 = 26 cm. If the sum of all sides of the is 50, and the left and right sides of the triangle are 26, the triangle base is 50 - 26 = 24 cm. The answer is 24.

Two shirts costs $7 x 2 = $14. The cost of a pair of shoes is $7 + $3 = $10. The total cost of two shirts a pair of shoes is $14 + $10 = $24. The cost of a bag is $24 / 2 = $12. So, Sofia paid a total of $14 + $10 + $12 = $36. The answer is 36.
