Question

an accountant charges a fee of $100 to complete a companys taxes. the accountant also charges an additional $35 per hour to complete the taxes. which of the following equations can be used to describe this problem?
a $y = 35 - 100x$
b $y = 35 + 100x$
c $y = 100 - 35x$
d $y = 100 + 35x$

Explanation:

Step1: Define variables

Let $x$ = number of hours, $y$ = total fee.

Step2: Identify fixed fee

Fixed cost = $100 (constant term).

Step3: Identify variable cost

Hourly rate = $35, so variable cost = $35x$.

Step4: Build total cost equation

Total fee = fixed fee + variable cost: $y = 100 + 35x$

Answer:

d. $y = 100 + 35x$
