The invested money by uncle Sammy = $2,300.
Uncle Sammy makes minimum percent = 7 %.
So, let us calculate the minimum amount Uncle Sammy can make to invest $2,300 at 7%.
7% of 2,300 = 0.07 * 2,300 = $161.
Uncle Sammy makes maximum percent = 13 %.
So, let us calculate the maximum amount Uncle Sammy can make to invest $2,300 at 13%.
13% of 2,300 = 0.13 * 2,300 = $299.
Therefore, the $161 - $299 is the range of money uncle Sammy will make if he invests his next paycheck of $2,300.
The lowest grade he could earn is 120% of the grade at the end of the semester.
The following statement is given:
I have 90% after about 75% of the semester.
We are asked to find the lowest grade by the end of this semester.
<h3>What is Percentage?</h3>
A percentage is a number expressed as a fraction of 100.
- 50% = 50/100 = 1/2
- 25% = 25/100 = 1/4
- 20% = 20/100 = 1/5.
We can write this statement "I have a 90% grade after about 75% of the semester" as:
90% grade = 75% semester.............(1)
By the end of the semester means at 100% semester.
Multiplying equation (1) by 100/ 75 on both sides of the equation.
We get,
(100/75) x 90% grade = (100/75) x 75% semester
(100 x 90)/75 % grade = 100% semester
120% grade = 100%
Thus the lowest grade he could earn is 120% of the grade at the end of the semester.
