Question

An employee receives a weekly salary of $340 and a 6% commission on all sales.

 

 

 

a. Write a rule to describe the function f(d) that gives weekly earning in terms if d dollars in sales.


b. Find the employee's earning for a week with $660 total sales.


c What were the employee's total sales for a week in which her earning were $1300?

Answer 1

Weekly earnings can be expressed as a function f(d) such that:

 

f(d) = 340 + .06d because 6% = 0.06. 

 

If there were $660 in sales, then f(d) = 340 + .06(660) = 340 + 39.6 = $379.60

 

If weekly earnings were $1300, then:

 

f(d) = 1300 = 340 + .06d We now need to solve for d. 

 

1300 = 340 + .06d

960 = .06d

$16,000 = d
