Venus is at the deli to get subs for a party. She needs 81 inches of sub. The shop sells 5 and 8 inch subs. If she buys two 8 inch subs, how many 5 inch subs does she need to buy?
Let's think: The two 8 inch subs total 16 inches because 2 x 8 = 16. She still needs 65 inches of sub because 81 - 16 = 65. She needs to buy 13 five inch subs because 65 / 5 = 13.. The answer is: 13.

A gym charges its members $18 twice a month. If it has 300 members how much does it make a month?
Let's think: Each person is charged 18 * 2 = $36 per month. So they get 36 * 300 = $10,800 per month.. The answer is: 10800.

Hooper Bay has twice as many pounds of lobster than the two other harbors combined. If the other two harbors have 80 pounds of lobster each, how many pounds of lobster are the three harbors holding?
Let's think: Since the other two harbors have 80 pounds of lobsters each, they have a total of 80 + 80 = 160 pounds of lobster. Since Hooper Bay has two times more lobsters than the other two harbors combined, it has 2 * 160 = 320 pounds of lobster. In total, the three harbors have 320 + 160 = 480 pounds of lobster.. The answer is: 480.

Nine members of the crafts club are making 2 necklaces each. It takes 50 beads to make each necklace. How many beads will they need in all?
