Q: Ann is baking cookies. She bakes three dozen oatmeal raisin cookies, two dozen sugar cookies, and four dozen chocolate chip cookies. Ann gives away two dozen oatmeal raisin cookies, 1.5 dozen sugar cookies, and 2.5 dozen chocolate chip cookies. How many total cookies does she keep?
A: Ann had 3 dozen oatmeal cookies - 2 dozen = 1 dozen oatmeal cookies left. Ann had 2 dozen sugar cookies - 1.5 dozen = .5 dozen sugar cookies left. Ann had 4 dozen chocolate chip cookies - 2.5 dozen = 1.5 dozen chocolate chip cookies left. Ann has a total of 1 + .5 + 1.5 dozen cookies = 3 dozen cookies. 3 dozen cookies is 3 * 12 cookies = 36 cookies remaining. The answer is 36.
Question: In a Volleyball competition, Lizzie was able to score 4 points. Nathalie's score is 3 more than Lizzie's score and Aimee's score is twice the score of Lizzie and Nathalie combined. The rest of the points were made by their teammates. If the whole team was able to score 50 points, how many points did their teammates make?
Answer: Nathalie's score is 4 + 3 = 7. And the total points of Nathalie and Lizzie when combined is 7 + 4 = 11. So, the total score of Aimee is 11 x 2 = 22. Lizzie, Nathalie, and Aimee's total score is 22 + 11 = 33. Therefore, their teammates were able to score 50 - 33 = 17. The answer is 17.
[Question]3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with.
