1 answer:
Answer:
c = 208.8
Step-by-step explanation:
a. <em>To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.</em>
b. <em>You need to move the 7.2 to the other side. So, </em><em>multiply</em><em> both sides by 7.2, because it's being divided, so multiplying will cancel it out.</em>
c: <em>Then, multiply 7.2 by 29. (The * symbol means multiply)</em>
d. c. = 208.8 <em>The answer is 208.8, which is rounded to the tenths place.</em>
Hope this helps! I tried to explain it in detail. :)

Answer:
$16,000 at 8% annual interest.
$12,000 at 6% annual interest.
Step-by-step explanation:
Let x be amount invested at a rate of 8% annual interest and y be the amount invested at a rate of 6% annual interest.
We have been given that an executive invests $28000, some at 8% and the rest at 6% annual interest. We can represent this information as:
We are also given that he received annual return of $2000. We can represent this information as:
We will use substitution method to solve our system of equations. From equation (1) we will get,
Substituting this value in equation (2) we will get,
Therefore, the executive has invested $12,000 at a rate of 6% annual interest.
Upon substituting y=12,000 in equation (1) we will get,
Therefore, the executive has invested $16,000 at a rate of 8% annual interest.
