The Rotary Club is holding its annual fundraising Omelet Breakfast, with tickets sold in advance. The tickets come in different price levels, for young children, older children, adults, and seniors. This year they sold 53 small children tickets, 35 older children tickets, 75 adult tickets, and 37 senior tickets. To figure out how many eggs they need to buy, the club estimates that small children can eat a half omelet, older children can eat a whole omelet, adults will eat two omelets, and seniors will eat one and a half omelets. Just to be on the safe side, they get enough eggs to make 25 extra omelets. If they use 2 eggs for each omelet, how many eggs will they need to buy? Give the rationale and then the answer.
Let's think step by step. They'll need to make an estimated 0.5 * 53 = 26.5 omelets for small children. They'll need to make an estimated 1 * 35 = 35 omelets for older children. They'll need to make an estimated 2 * 75 = 150 omelets for the adults. And they'll need to make an estimated 1.5 * 37 = 55.5 omelets for the seniors. Along with the 25 extra omelets they'll make as a buffer, they will need enough eggs for 26.5 + 35 + 150 + 55.5 + 25 = 292 omelets. So they will need 2 * 292 = 584 eggs.. The answer is: 584.

Lisa, Jack, and Tommy earned $60 from washing cars all week. However, half of the $60 was earned by Lisa. Tommy earned half of what Lisa earned. How much more money did Lisa earn than Tommy? Give the rationale and then the answer.
Let's think step by step. Lisa earned $60 * 1 / 2 = $30. Tommy earned $30 * 1 / 2 = $15. Lisa earned $30 - $15 = $15 more than Tommy.. The answer is: 15.

Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads. How many bracelets can Nancy and Rose make? Give the rationale and then the answer.
Let's think step by step. Nancy has 40 + 20 = 60 pearl beads. So, Nancy has a total of 40 + 60 = 100 beads. Rose has 2 x 20 = 40 stone beads. So, Rose has 20 + 40 = 60 beads. Thus, Nancy and Rose have 100 + 60 = 160 beads altogether. Therefore, they can make 160 / 8 = 20 bracelets.. The answer is: 20.
