There are 3 consecutive odd integers that have a sum of -147. What is the largest number?
Let's think: Let N = smallest number. N + 2 = next number. N + 4 = largest number. N + (N + 2) + (N + 4) = - 147. 3N + 6 = - 147. 3N = - 153. N = - 51. The largest number is - 47.. The answer is: -47.

One afternoon, Rachelle, Gretchen and Rocky threw pennies into the fountain and made wishes. Rachelle threw 180 pennies into the fountain. Gretchen threw half as many pennies into the fountain as Rachelle and Rocky threw in one-third as many pennies as Gretchen. What was the total number of pennies thrown into the fountain by the three of them?
Let's think: Gretchen threw half as many pennies into the fountain as did Rachelle, for a total of 180 / 2 = 90 pennies. Rocky threw one - third as many as Gretchen, for a total of 90 / 3 = 30 pennies. In total, the three threw 180 + 90 + 30 = 300 pennies into the fountain.. The answer is: 300.

John's new computer cost $1500. He needs to get a monitor and other peripherals that cost 1/5 that much. He also wants to upgrade the $300 video card in the base computer with one that costs twice as much. How much did he spend?
Let's think: The peripherals cost 1500 / 5 = $300. The video card cost 300 * 2 = $600. So it cost 600 - 300 = $300 more. That means the total cost was 1500 + 300 + 300 = $2100.. The answer is: 2100.

Tommy wants to earn enough money to buy 8 new books. Each book costs $5. If Tommy already has $13, how much does he need to save up?
Let's think:
The books will cost $40 because 8 x 5 = 40. He needs to save up $27 because 40 - 13 = 27.. The answer is: 27.
