Q1. Growth of sales between the years
Ans. 
The sales growth between the years is calculated by comparing the sales figures from one year to another.
• Calculate the difference in sales between the two years

• Divide the difference by the sales figure of the initial year

• Multiply the result by 100 to get the percentage growth

• For example, if sales were $100 in year 1 and $120 in year 2, the growth would be (120-100)/100 * 100 = 20%
