Answer:
26.67%.
Step-by-step explanation:
We are asked to find the percent increase in number of accidents from 1967 to 1968.
[tex]\text{Percent increase}=\frac{\text{Final }-\text{ Original}}{\text{Original}}\times 100[/tex]
[tex]\text{Percent increase}=\frac{380-300}{300}\times 100[/tex]
[tex]\text{Percent increase}=\frac{80}{3}[/tex]
[tex]\text{Percent increase}=26.6666\%[/tex]
[tex]\text{Percent increase}=26.67\%[/tex]
Therefore, the percent increase in number of accidents is 26.67%.
