Two construction companies put in bids for a job reworking the HVAC system in an old building. Company A charges $2,000 plus $75 per vent, while company B charges $3,500 plus $45 per vent. How many vents would need to be cleaned for company B to be the cheaper option?

answer: what are the following choices

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:

8 < i think

hope this !

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
