Answer:
120%
Step-by-step explanation:
Given net sales;
Year 1996 = $690000
Year 1997 = $730000
Year 1998 = $828000
With 1996 as the base year, it means the percentage of any year can be computed by dividing the net sales for that year with the net sales for 1996 and expressing the results as a percentage.
1998 sales as a percentage of the base represents
= $828000/$690000
= 1.2
Expressed as a percentage, this is 120%.
