At the Conic Company, a new employee's earnings E, in dollars, can be calculated using the function E = 0.05s + 30,000, where s represents the employee's total sales, in dollars. All of the new employees earned between $50,000 and $60,000 last year. Which value is in the domain of the function? Please show your workA $34,000 B $300,000 C $430,000 D $3,400,000
Answers
we know that E is in between 50,000 and 60,000. we substitute this in and find the values of s, which are 400,000 and 600,000. This becomes the domain therefore C is the answer.
50,000=0.05s+30,000 20,000=0.05s 400,000=s
60,000=0.05s+30,000 30,000=0.05s 600,000=s
since E is in-between $50,000 and $60,000, s is in between 400,000 and 600,000, which is the domain. C is the answer.
