Answer this question:Marnie makes bead bracelets. She bought 5 bags of 50 beads and 2 bags of 100 beads. If 50 beads are used to make one bracelet, how many bracelets will Marnie be able to make out of the beads she bought?
Marnie bought 50 x 5 = 250 beads from the 5 bags of 50 beads. She also bought 100 x 2 = 200 beads from the 2 bags of 100 beads. She has a total of 250 + 200 = 450 beads. Hence, she will be able to make 450 / 50 = 9 bracelets.
The answer is 9.

Answer this question:8 jumbo scallops weigh one pound and cost $24.00 a pound. Nate is pairing 2 scallops with a corn bisque as a light summer dinner. He’s cooking for 8 people. How much will the scallops cost?
He’s cooking for 8 people and wants to serve 2 scallops per person so he needs 8 * 2 = 16 scallops. 8 jumbo scallops come in 1 pound and he needs 16 scallops so he will need 16 / 8 = 2 pounds of scallops. A pound of scallops weigh $24.00 and he needs 2 pounds so it will cost him 24 * 2 = $48.00 for scallops.
The answer is 48.

Answer this question:Sonja makes her own peanut butter with peanuts and oil in a blender. She uses a ratio of two ounces of oil to smooth out every eight ounces of peanuts. Her last batch of peanut butter weighed 20 ounces. How many ounces of oil did she use?
Sonja uses 2 ounces of oil for 8 ounces of peanuts to make 2 + 8 = 10 ounces of peanut butter. Her last batch weighed 20 ounces, so she made 20 / 10 = 2 times her ratio. Thus, she used 2 * 2 = 4 ounces of oil.
The answer is 4.

Melony makes $21 * 4 = $84 of profit for two pairs of sandals. Melony makes $84 / 2 pairs = $42 of profit per pair of shoes. Melony makes $21 / 3 shirts = $7 of profit per shirt. For seven shirts, Melony will make 7 shirts * $7 = $49 of profit. For three pairs of sandals, Melony will make 3 pairs * $42 / pair = $126 of profit. Melony will make a total of $49 + $126 = $175 of profit.
The answer is 175.
