Well 3 packs for 6 dollars is 2 dollars a pack. while 2 packs for 5 dollars is 2.5 dollars a pack
You would subtract the tax first which 62.99-2.99=60$. Then you would divide the $60 left by 6 and 60 divided by 6 equals 10 so each shirt costs $10.
10 is the default base for a logarithm
log of 50 is equal to log base 10 of 50
The answer is B
I know this because 8 divided by -4 =-2
Therefore the answer is: B
