Question: Ajax is 80 kilograms. He is planning to lose some weight. Exercising for an hour will help him lose 1.5 pounds. If 1 kilogram is equal to 2.2 pounds How many pounds will he weigh if he exercises for 2 hours every day for two weeks?
Answer: Step-by-step reasoning process: Ajax weighs 80 x 2.2 = 176 in pounds. He will lose 1.5 x 2 = 3 pounds per day. So he will lose 3 x 7 = 21 pounds per week. So, he will lose 21x 2 = 42 pounds after 2 weeks. Therefore, he will weigh 176 - 42 = 134 pounds after 2 weeks.
So the answer is 134.

Question: Mrs. Brynlee reduced the prices of items in her store by 20% after the local government gave small businesses in her county a subsidy. If the price of a shirt in the store was $60 and that of the leather jacket was $90, calculate the amount of money Teagan will pay for buying 5 shirts and 10 leather jackets at the reduced prices.
Answer:
Step-by-step reasoning process: If the price of a shirt in the store was $60, its price was reduced by 20 / 100 * $60 = $12. The price of a shirt was reduced to $60 - $12 = $48. Teagan will pay $48 * 5 = $240 for buying 5 shirts. If the initial price of the leather jacket was $90, the price reduced by 20 / 100 * $90 = $18. The final leather jacket after Mrs. Brynlee reduced the price by 20% is $90 - $18 = $72. Teagan will pay $72 * 10 = $720 for buying 10 leather jackets. The amount of money Teagan paid to Mrs. Brynlee for the shirts and the leather jackets is $720 + $240 = $960.
So the answer is 960.
