Answer:
50.16%
Step-by-step explanation:
The percentage increase in sales from the preceding year to the current year can be calculated as:
![(P_c-P_p)/(P_p)\cdot 100](https://img.qammunity.org/2021/formulas/business/college/f99h2rdzavferk13ynt6rtli3ibmbgxgy1.png)
where:
is the sale for the current year
is the sale for the preceding year
From the sales data of this problem, we have:
(current year)
(preceding year)
Therefore, the percentage increase in sales is:
![(764,442-509,074)/(509,074)\cdot 100=50.16\%](https://img.qammunity.org/2021/formulas/business/college/7ts1demkabkcbuzpzi6soizee1mkx56623.png)
