How do you express 6% of a number, d?

anonymous · Answer

d=.06%

anonymous · Answer

Sorry, wrong key...d*.06%

mathstudent55 · Answer

Correct. 6% is 0.06, and 6% of d is 0.06d.
That's great.

mathstudent55 · Answer

This person earns a fixed $340 per week.
So far f(d) = 340
The person also earns 6% on d dollars, that you know is 0.06d.
That means the weekly salary is:
f(d) = 340 + 0.06d
Ok?
