Answer:
Option (b) is correct.
Step-by-step explanation:
Sale value of the merchandise = $74,900
Sales tax liability = $74,900 × (7% ÷ 107%)
= $4,900
Sale value prior to sales tax = $74,900 - $4,900
= $70,000
Sales tax @7% on $70,000 = $4,900
Hope the above calculation will clear the concept since the question clearly mention that
Calhoun Crockery sold merchandise; the total proceeds collected, including a 7% sales tax, amounted to $74,900.
This $74,900 includes 7% tax also it means that the collected proceed is 100% + 7% = 107%
which includes 7% tax liability.
