A phone company offers a deal by which a long distance phone call costs .99 cents for the first 20 minutes and .07 per minute thereafter. Write a piecewise-defined function for the cost C of making a phone call that lasts x minutes.
So I did this:
f(x) { .99(6) 0<= x
.99(20) 0=> x >= 20
Not a clue what I'm doing...
