Question: The rate for mowing a lawn is $14 per hour. David mowed for 2 hours a day for a week. He then spent half of the money he made from mowing a lawn on a pair of shoes and gave half of the remaining money to his mom. How much money did he have left?
Answer with step-by-step thinking: David got $14 / hour x 2 hours / day = $28 per day from mowing. So in a week, he had $28 / day x 7 days = $196. A pair of shoes cost $196 / 2 = $98. David gave his mom $98 / 2 = $49. The total amount he spent and gave is $98 + $49 = $147. David is left with $196 - $147 = $49.
So the answer is 49.


Question: Nina wants to buy a new video game with her allowance money. The game cost 50 dollars. Nina also has learned that there is a 10 percent sales tax. She receives 10 dollars a week as an allowance, and thinks she can save half of that. How many weeks will it take for Nina to be able to buy the new video game with her savings?
Answer with step-by-step thinking: The 10 percent tax on 50 dollars will be 10 / 100 x 50 = 5 dollars. The cost of the game and the tax will be 50 + 5 = 55 dollars. Nina will save half of her allowance every week, or 10 / 2 = 5 dollars per week. The total cost of the game and tax, divided by Nina's weekly savings is 55 / 5 = 11 weeks.
So the answer is 11.


Question: In the baking contest, three times as many people voted for the unicorn cake compared to the witch cake, and the number of votes for the dragon cake was 25 more than the number of votes for the witch cake. If 7 people voted for the witch cake, how many votes were cast total?
Answer with step-by-step thinking:
First find the number of votes for the unicorn cake: 7 votes * 3 = 21 votes. Then find the number of votes for the dragon cake: 25 votes + 7 votes = 32 votes. Then add the number of votes for each cake to find the total number of votes: 21 votes + 32 votes + 7 votes = 60 votes.
So the answer is 60.
