Mr. Williams ordered s T-shirts printed with his school's logo. An equation for the total cost of s T-shirts is C = 8s + 100. Mr. William rewrote the equation in a different form, to emphasize that the first 25 T-shirts cost $12 each, and any additional T-shirts cost $8 each. Which of the following could be his equation?

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

step-by-step explanation:

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:
