Q: Moore's family compared mobile phone plans to get the best deal. At T-Mobile, the family plan costs $50 per month for the first two lines and $16 for each additional line. At M-Mobile, the family plan costs $45 for the first two lines and $14 for each additional line. Moore's family needs to purchase 5 cell phone lines. How much cheaper is the M-Mobile than T-Mobile?
A: The three additional lines at T - Mobile cost $16 x 3 = $48. The total cost of the family plan at T - Mobile is $50 + $48 = $98. The three additional lines at M - Mobile cost $14 x 3 = $42. The total cost of the family plan at M - Mobile is$45 + $ 42 = $87. Therefore, M - Mobile is $98 - 87 = $11 cheaper than T - Mobile. The answer is 11.
Question: Donna cut her pizza into 12 slices and ate half for lunch. She ate 1/3 of the remaining pizza for dinner. How many slices are left for Donna's lunch tomorrow?
Answer: Her pizza has 12 slices and she ate 1 / 2 of the pizza for lunch so that leaves 12 / 2 = 6 slices left. She eats 1 / 3 of the pizza for dinner, so she eats 1 / 3 * 6 = 2 slices. She had 6 slices and ate 2 slices, so that leaves her with 6 - 2 = 4 slices for tomorrow's lunch. The answer is 4.

Q: There are 50 apples and 40 oranges in the cafeteria. If an apple costs $0.80 and an orange costs $0.50, how much does the cafeteria earn for apples and oranges if there are only 10 apples and 6 oranges left?
A: Counting the remaining 10 apples. There were 50 - 10 = 40 apples sold. Counting the remaining 6 oranges. There were 40 - 6 = 34 oranges sold. The amount of sales for the apples is $0.8 x 40 = $32. The amount of sales for the oranges is $0.5 x 34 = $17. The cafeteria's total earnings are $32 + $17 = $49. The answer is 49.
Question: Hilary is collecting her toenails in a jar to gross out her sister. She can fit 100 toenails in the jar, unless they are from her two big toes, which are twice as big as the rest. She has already filled it with 20 big toenails and 40 regular toenails. How many regular toenails can she fit into the remainder of the jar?
Answer: The 20 big toenails take up as much space as 40 regular toenails because 20 x 2 = 40. She has filled up 80 toenails worth because 40 + 40 = 80. She can fit 20 regular toenails in the jar because 100 - 80 = 20. The answer is 20.
Q: There were 50 fish in a pond and 3 times as many tadpoles. If Curtis catches 7 fish and half the tadpoles develop into frogs, how many more tadpoles than fish are there in the pond now?
