Answer:

The percent of change is 23% ( approx )

Step-by-step explanation:

Given,

The original value = 9.8,

New value = 12.1

Thus,

[tex]\text{The percentage change}=\frac{\text{New value-original value}}{\text{Original value}}\times 100[/tex]

[tex]=\frac{12.1-9.8}{9.8}\times 100[/tex]

[tex]=\frac{230}{9.8}[/tex]

[tex]=23.4693877551\%[/tex]

[tex]\approx 23\%[/tex]
