For the Item that costs $64 before tax the sales tax is $6
Hence for the item that costs $1 before tax the sales tax is $(6/64), by the rule of proportions or unitary method
Hence for the item that costs $100 before tax the sales tax is $[100*(6/64)], by the rule of proportions
which is = $75/8 or $9.45
Therefore, the item having a Sales tax of $9.45 or $75/8 costs $100 before tax
thus the item having a Sales tax of $1 costs $[(100*8)/75] before tax, by the rule of proportions or unitary method
thus the item having a Sales tax of $8.25 costs $[(100*8*8.25)/75] before tax, by the rule of proportions
which is = $88

The answer is the second choice
Answer:
g(3a – 6) = a - 4
Step-by-step explanation:
g(x) = 1/3x - 2
g(3a – 6) = 1/3(3a – 6) - 2
= a - 2 - 2
= a - 4
