answer: c. is your answer

step-by-step explanation: get me a black leather coat

answer: 1475

step-by-step explanation:

becuase you have to know what they are asking you

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:
