For every 5 people that attend a poetry class, the teacher gives one of the students a lollipop. If 45 people show up for class, then another 15 come in a while later, how many lollipops did the teacher give away?
Let's think: The teacher has 45 + 15 = 60 people come in total. For every 5 people, a lollipop is given away so there are 60 / 5 = 12 groups of 5 people and 12 lollipops given away.. The answer is: 12.

Penn operates an ice cream stall for a week. On the first day, she made $10. Every day after that, she made $4 more than the previous day. How much money did Penn make after 5 days?
Let's think: On the second day, Penn made $10 + $4 = $14. On the 3rd day, she made $14 + $4 = $18. On the 4th day , she made $18 + $4 = $22. On the 5th day, she made $22 + $4 = $26. After 5 days, Penn made a total of $10 + $14 + $18 + $22 + $26 = $90.. The answer is: 90.

A play was held in an auditorium and its ticket costs $10. An auditorium has 20 rows and each row has 10 seats. If only 3/4 of the seats were sold, how much was earned from the play?
Let's think: There are 20 x 10 = 200 seats in the auditorium. Only 200 x 3 / 4 = 150 seats were sold. Hence, the earnings from the play is $10 x 150 = $1500.. The answer is: 1500.

Jake splits 8 shots of vodka with his friend. Each shot of vodka is 1.5 ounces. If the vodka is 50% pure alcohol, how much pure alcohol did Jake drink?
Let's think:
Jake drank 8 / 2 = 4 shots. So he drank 4 * 1.5 = 6 ounces of vodka. That means he drank 6 * .5 = 3 ounces of pure alcohol.. The answer is: 3.
