Bob and Jim decide to skip rocks. Bob can skip a rock 12 times. Jim can skip a rock 15 times. If they each skipped 10 rocks how many total skips did they get?
Let's think: Bob got 12 * 10 = 120 skips. Jim got 15 * 10 = 150 skips. So in total they got 120 + 150 = 270 skips.. The answer is: 270.

Solomon collected three times as many cans as Juwan. Levi collected half of what Juwan collected. Solomon collected 66 cans. How many cans did the boys collect in all?
Let's think: Solomon is 3 * Juwan so Juwan is 1 / 3 of Solomon = 66 / 3 = 22. Levi collected half of 22 = 11. Combined the boys collected 66 + 22 + 11 = 99 cans in all.. The answer is: 99.

Greta received 10 more letters in the mail than her brother. Greta's mother received twice the total number of letters Greta and her brother received. Calculate the total number of letters the three received if Greta's brother received 40 letters.
Let's think: Since Greta's brother received 40 letters, Greta received 40 + 10 = 50 letters. Together, Greta and her brother received 50 + 40 = 90 letters. Greta's mother received twice the total number of letters Greta and her brother received, which totals 90 * 2 = 180 letters. In total, the three received 90 + 180 = 270 letters.. The answer is: 270.

Kristy, a sales representative earns a basic salary of $7.50 per hour plus a 16% commission on everything she sells. This month, she worked for 160 hours and sold $25000 worth of items.

Kristy earns a basic salary of $7.50 x 160 = $1200. Her total commission is $25000 x 16 / 100 = $4000. Thus, her total earning is $1200 + $4000 = $5200. Her monthly budget aside from the insurance is $5200 x 95 / 100 = $4940. Therefore, she allocated $5200 - $4940 = $260 on insurance.. The answer is: 260.
