Q: Zach is saving his money to buy a brand new bike that costs $100. His weekly allowance is $5. His parent will pay him an extra $10 to mow the lawn. His neighbor will pay him $7 per hour to babysit their son. He has already saved up $65. He'll receive his allowance on Friday and he's planning on babysitting for 2 hours this Saturday after he mows the lawn. How much more money does Zach need to earn before he can buy the bike?
A: If he babysits for 2 hours at $7 per hour, he will earn 2 * 7 = $14. This week he will earn $5 allowance, $10 mowing the lawn and $14 from babysitting for a total of 5 + 10 + 14 = $29. If we add the $29 he will earn to his $65 savings, he will have a total of 29 + 65 = $94. The bike costs $100 and he will have $94 leaving $100 - $94 = $6 more that he will need to earn. The answer is 6.
Question: Peggy is moving and is looking to get rid of her record collection. Sammy says that he will buy all of them for 4 dollars each. Bryan is only interested in half of the records but will offer 6 dollars each for the half that he is interested in and 1 dollar each for the remaining half that he is not interested in with the hopes that he can resell them in bulk later. If Peggy has 200 records, what is the difference in profit between Sammy versus Bryan's deal?
Answer: Sammy is offering to take the whole collection of 200 records and pay Peggy 4 dollars each for them which would net Peggy 200 * 4 = 800 dollars for her entire record collection. Bryan is willing to buy Peggy's entire record collection but at two different price points, half at one point and half at another. Half of Peggy's record collection is 200 / 2 = 100, which means that 100 records will sell for one price and 100 records will sell for another price. Bryan is willing to pay more for the half of the record collection that he is interested in so Peggy would net 100 * 6 = 600 dollars for the first half of her record collection. For the half of the collection that Bryan is just planning on reselling at a later date, he is willing to offer Peggy 100 * 1 = 100 dollars to take off of her hands. In total Bryan is willing to offer Peggy 600 + 100 = 700 dollars for her entire record collection. If Sammy is offering 800 dollars to buy Peggy's entire record collection and Bryan is offering 700 dollars for Peggy's entire record collection, then Peggy's net profit would be 800 - 700 = 100 dollars more by taking Sammy's deal instead of Bryan's deal. The answer is 100.

Q: A quarterback throws 50 passes in one game. He throws twice as many passes to the right of the field than he does to the left of the field. He throws 2 more passes to the center of the field than he did to the left. How many passes did he throw to the left side of the field?
A: Let x represent the number of passes thrown to the left side of the field. Right:2x. Center:x + 2. Total:x + 2x + x + 2 = 50. 4x + 2 = 50. 4x = 48. x = 12 passes. The answer is 12.
Question: Uki owns a bakery. She sells cupcakes at $1.50 each, cookies at $2 per packet, and biscuits at $1 per packet. In a day, she can bake an average of twenty cupcakes, ten packets of cookies, and twenty packets of biscuits. How much will be her total earnings for five days?
Answer:
Uki earns 20 x $1.50 = $30 in selling 20 cupcakes. She earns 10 x $2 = $20 for selling 10 packets of cookies,. Additionally, she earns another 20 x $1 = $20 for selling twenty packets of biscuits. Thus, in a day, she earns an average of $30 + $20 + $20 = $70. Therefore, for five days, Uki earns 5 x $70 = $350. ". The answer is 350.
