HHT1 Finite Math Applications

Task A. 1. To determine if Student1 has enough points to achieve at least 90% I created a ratio based on the number of points needed to get a grade of 100% and the number of points earned by Student1. 334/100 = 299/n 334n = 29900 n = 89.52095808

89.52095808 rounded to a whole number is 90%, due to the 5 in the tenths place which causes the number to be rounded up. The teacher will give Student1 with 299 points in the term an A in the class.

2. Student1 would not have received an A for the class if the teacher had truncated the percentage to a whole number. The percentage of 89.52095808 truncated to a whole number would equal 89% which would not satisfy the requirement of at least 90% to get an A for Student1.

3. Teaching middle school mathematics

Before starting to explain the course material I would have a brief discussion with the children to get a gauge on their knowledge of taxes. I would create a few scenarios to explain taxing and basic percentages in a fun way. In order to develop a general understanding of the subject and to introduce new terminology.

Truncating a number is when you remove all digits beyond a certain position without rounding. A taxpayer whose income tax rate is 27.8% would hope that their tax rate be truncated because their tax rate would then be 27%. Having a tax rate of 27% would allow the taxpayer to keep the difference of .8% in their pocket. For example, if Ms. Jones is making $50,000 a year and was taxed at 27.8% she would pay $13,900 income tax. If Ms. Jones income tax rate was truncated to a whole number her salary of $50,000 would then be taxed at 27% and she would pay $13,000 income tax. Mrs. Jones would be saving $400 by having her income tax rate truncated to a whole number.

The government prefers and requires taxpayers to round the tax rate to be rounded because it prevents them from losing income tax revenue and works out in their favor. If the income tax rate were truncated...
