Question: On each of 7 Mondays, it rained 1.5 centimeters. On each of 9 Tuesdays it rained 2.5 centimeters. How many more centimeters did it rain on Tuesdays than Mondays?
Answer with step-by-step thinking: Mondays: 7 * 1.5 = 10.5. Tuesdays: 9 * 2.5 = 22.5. 22.5 - 10.5 = 12 cm. It rained 12 centimeters more on Tuesdays than on Mondays.
So the answer is 12.

Question: Twice the money Jericho has is 60. He owes Annika $14 and also owes half as much to Manny. After paying off all his debts, how much money will Jericho be left with?
Answer with step-by-step thinking: Jericho has $60 / 2 = $30. He owed Manny $14 / 2 = $7. His debts amount to $14 + $7 = $21. So Manny will have $30 - $21 = $9 left.
So the answer is 9.

Question: John buys 500 newspapers. Each newspaper sells for $2. He sells 80% of them. He buys them all for 75% less than the price at which he sells them. How much profit does he make?
Answer with step-by-step thinking:
He sells 500 * .8 = 400 newspapers. He sells them for 400 * 2 = $800. He gets a discount of 2 * .75 = $1.5 on the newspapers. So he buys them for 2 - 1.5 = $.5. So he spent 500 * .5 = $250 buying them. That means he made a profit of 800 - 250 = $550.
So the answer is 550.
