Q: Maya wants to learn how to lift and right now she can only lift a fourth of what America can. America can lift 240 pounds. As Maya grows stronger, she can add 10 more pounds to what she previously could lift. America follows this and now she has hit her peak lift at 300 pounds. If Maya reaches her absolute peak and can lift half of what America can lift, how many more pounds can Maya lift now than when she started?
A: Maya can lift 240 * 0.25 = 60 pounds. Gaining progress, she can lift up to 60 + 10 = 70 pounds. At her peak, she can lift 300 * 0.5 = 150 pounds. Maya's peak is 150 pounds - 60 pounds when she started = 90 more pounds than when she started. The answer is 90.
Question: John works 12 hours every other day. He gets a 30% raise from his former $20 an hour job. How much does he make in a 30 day month?
Answer: He works 30 / 2 = 15 days. So he works 15 * 12 = 180 hours in the month. He got a 20 * .3 = $6 an hour raise. So he gets paid 20 + 6 = $26 an hour. That means he makes 26 * 180 = $4680. The answer is 4680.
[Question]James and 4 of his friends volunteered to plant flowers. In 2 days, they were able to plant a total of 200 flowers. If each of them planted the same number of flowers, how many flowers did James plant in a day?
[Answer]There were 1 + 4 = 5 of them who volunteered to plant flowers. Each day, the 5 of them planted a total of 200 / 2 = 100 flowers. Thus, James planted 100 / 5 = 20 flowers in a day. The answer is 20.
Q: Chloe and Max played Mario Kart together. The ratio of Chloe’s wins to Max’s wins is 8:3. Chloe won 24 times. How many times did Max win?
A: We are trying to figure out how many times Max won at Mario Kart, so we'll call that number Y. We know the ratio of Chloe’s wins to Max’s wins is 8 / 3, so 8 / 3 = 24 / Y. Next, we will multiply to find the cross - products. 8 x Y = 3 x 24 or 8Y = 72. We want to get figure out Y, so we need to get it by itself by dividing by 8, like this: 8Y / 8 = 72 / 8. Y = 9, so Max won 9 times. The answer is 9.
Question: At a party, there are 50 people. 30% of them are boys. How many girls are at this party?

Q: Two stores sell the same model of smartphone, but they offer it at different prices and with different discounts. Store A lists the smartphone at a full price of $125 and offers an additional discount of 8%. Store B lists the same smartphone for $130 and offers an additional discount of 10%. After both stores' discounts are applied, how much cheaper is store A's smartphone than store B's smartphone?
A:
Store A has a $125 x 8 / 100 = $10 discount. So the smartphone from store A will only cost $125 - $10 = $115. Store B has a $130 x 10 / 100 = $13 discount. So the smartphone from store B will only cost $130 - $13 = $117. Thus, store A's smartphone is $117 - $115 = $2 cheaper than that of store B. The answer is 2.
