7. Booker Bond demonstrates cookware at the National Food Fair. He is paid $6.00 each for the first 10 demonstrations in one day and $7.50 for each
demonstration over 10. What is Bond's commission for a day in which he
makes 21 demonstrations?

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
