Question: Marla is planning the lunch menu for an elementary school. There are 5 third grade classes with 30 students each, 4 fourth grade classes with 28 students each, and 4 fifth grade classes with 27 students each. Each student gets a hamburger, which costs $2.10, some carrots, which cost $0.50, and a cookie, which cost $0.20. How much does one lunch for all the students cost?
Answer with step-by-step thinking: First find the total number of students in third grade 5 classes * 30 students / class = 150 students. Then find the total number of students in fourth grade 4 classes * 28 students / class = 112 students. Then find the total number of student in fifth grade 4 classes * 27 students / class = 108 students. Now add the number of students in each grade to find the total number of students 150 students + 112 students + 108 students = 370 students. Now find the total cost of one lunch $2.10 + $0.50 + $0.20 = $2.80. Now multiply that cost by the number of students to find the total cost for the school $2.80 / student * 370 students = $1036.
So the answer is 1036.

Question: Dabbie bought 3 turkeys for thanksgiving, the first turkey is 6 kilograms, the second turkey is 9 kilograms, and the weight of the third turkey is twice the weight of the second turkey. If the cost of a kilogram of turkey is $2, how much does Dabbie spent on all the turkeys?
Answer with step-by-step thinking: Dabbie paid 6 x $2 = $12 for the first turkey. He paid 9 x $ 2 = $18 for the second turkey. And the weight of the third turkey is 9 x 2 = 18 kilograms. So, the price of the third turkey is 18 x $2 = $36. Therefore, the total amount he paid for all the turkeys is $12 + $18 + $36 = $66.
So the answer is 66.

Question: Melly's two cats each have litters of kittens at the same time. The first cat has 3 blue-eyed kittens and 7 brown-eyed kittens. The second cat has 4 blue-eyed kittens and 6 brown-eyed kittens. What percentage of all the kittens have blue eyes?
Answer with step-by-step thinking:
First find the total number of blue - eyed kittens: 3 kittens + 4 kittens = 7 kittens. Then find the total number of brown - eyed kittens: 7 kittens + 6 kittens = 13 kittens. Then add the number of each type of kitten to find the total number of kittens: 7 kittens + 13 kittens = 20 kittens. Then divide the number of blue - eyed kittens by the total number of kittens and multiply by 100% to express the answer as a percentage: 7 kittens / 20 kittens * 100% = 35%.
So the answer is 35.
