[Question]: An employee makes 30 dollars an hour for the first 40 hours in the workweek and an additional 50% for every hour above 40 in the week. If he works 6 hours for the first 3 days in the workweek and twice as many hours per day for the remaining 2 days, how much money did he make?
[Answer]: His overtime pay per hour is 30 * 1.5 = $45 per hour. He works 6 * 2 = 12 hours per day for the last two days. He works 6 + 6 + 6 + 12 + 12 = 42 hours. He gets 42 - 40 = 2 hours of overtime. He makes 40 * 30 + 2 * 45 = $1290 for the week.
So the answer is 1290.

[Question]: To support the school outreach program, Einstein wants to raise $500 by selling snacks. One box of pizza sells for $12, a pack of potato fries sells for $0.30, and a can of soda at $2. Einstein sold 15 boxes of pizzas, 40 packs of potato fries, and 25 cans of soda. How much more money does Einstein need to raise to reach his goal?
[Answer]: Einstein collected 15 x $12 = $180 for selling pizzas. He collected 40 x $0.30 = $12 for the 40 packs of potato fries. He collected 25 x $2 = $50 for the 25 cans of soda. Thus, the total amount section Einstein collected was $180 + $12 + $50 = $242. Therefore, Einstein needs $500 - $242 = $258 more to reach the goal.
So the answer is 258.

[Question]: Sarah buys 20 pencils on Monday. Then she buys 18 more pencils on Tuesday. On Wednesday she buys triple the number of pencils she did on Tuesday. How many pencils does she have?
[Answer]:
By adding together Monday and Tuesday, Saah has 20 + 18 = 38 pencils. On Wednesday, she buys 3 * 18 = 54 pencils. All together, Sarah has 38 + 54 = 92 pencils.
So the answer is 92.
