please somebody help me I really need help with this

Answer:
54.4 %
Explanation:
The percent change in net sales can be calculated as:
[tex]\text{ \% Change = }\frac{\text{ Final number - Initial number}}{\text{ Initial number}}\times100[/tex]Where the final number is the net sales in quarter 2 and the initial number is the net sales in quarter 1. Replacing the values by 170 and 110, we get:
[tex]\text{ \% Change = }\frac{170-110}{110}\times100=\frac{60}{110}\times100=54.5\text{ \%}[/tex]Therefore, the answer is:
percent change = 54.5 %
