question 9(multiple choice worth 4 points) (01 03 mc) to hire an accountant to prepare taxes costs a flat fee and an additional hourly rate. the amount the accountant costs can be modeled by the function a(x)=140 + 25x, where x represents the number of hours the accountant works to prepare the taxes and 140 represents the flat fee. what is the value of a(215) and its interpretation? a(215)=3; if the accountant takes 215 hours to prepare the taxes, the cost will be $2. a(215)=3; if the account takes 3 hours to prepare the taxes, the cost will be $215. a(215)=5515; if the accountant takes 215 hours to prepare the taxes, the cost will be $5,515. a(215)=5515; if the accountant takes 5,515 hours to prepare the taxes, the cost will be $215.

Answer

Answer:

C. $A(215)=5515$. If the accountant takes 215 hours to prepare the taxes, the cost will be $5,515$.

Explanation:

Step1: Substitute $x = 215$ into function

$A(x)=140 + 25x$, so $A(215)=140+25\times215$.

Step2: Calculate $25\times215$

$25\times215 = 5375$.

Step3: Calculate $A(215)$

$A(215)=140 + 5375=5515$. This means when the accountant works 215 hours (since $x$ represents hours), with a flat - fee of 140 and an hourly rate of 25, the total cost is 5515.
