Problem of the Week 07-24-17

Jul 24, 2017

Lower Elementary:

Question: John has 8 quarters. He buys a bottle of pop and gets 6 dimes in change. How much does the pop cost?

Solution:  Each quarter is worth 25¢, so 8 quarters are worth 200¢, or \$2.00. Each dime is worth 10¢, so 6 of them are worth 60¢. The bottle of pop costs the difference between the amount John pays and the amount of change he gets, so the pop is worth \$2.00 – \$0.60 = \$1.40.

Upper Elementary:

Question: Mila has ¾ of a pound of caramels. Nora has 0.2 pounds of caramels. How much do their caramels weigh altogether?

Solution:  One way to do this problem is to convert ¾ into a decimal in order to add it to the other decimal. Mila has ¾ = 0.75. Since 0.75 + 0.2 = 0.95, Nora and Mila have 0.95 pounds of caramels altogether.

Middle School:

Question: Lucas has an average score of 40 points on his five history quizzes. He scored 35, 44, 41, and 38 on the first four quizzes. How many points did he score on the last quiz?
