An artist sells a painting for 20.50 but uses 5.75 worth of materials to make it. what will the artist total earnings be for selling the painting, after considering the cost of materials

$14.93

Step-by-step explanation:

An artist sells a painting for $20.50

The cost of the material that he uses to make it  = $5.57

His total earnings = selling cost - making cost

                              = 20.50 - 5.57

                              = $14.93

Total earning of the artist would be $14.93

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:
