Answer:
The average last year was $96,220.
Explanation:
From the information provided, you know that the average monthly revenue at the Somerville Times represents 75% of last year's monthly average and you can use a rule of three to find the value that represents 100%:
72,165 → 75%
x ← 100%
x=(72,165*100)/75
x=96,220
According to this, the answer is that the average last year was $96,220.
