SOLUTION

To find the percentage increase, we need to know the percentage change

Recall that

[tex]\text{percentage change=}\frac{new\text{ amount-old amount}}{\text{old amount }}\times100\text{ \%}[/tex]

Where

[tex]\begin{gathered} \text{New amount=66} \\ \text{old amount=60} \end{gathered}[/tex]

Substitute into the formula above, we have

[tex]\begin{gathered} \text{percentage change=}\frac{\text{66-60}}{60}\times100\text{ \%} \\ \text{Then} \\ \text{percentage change=}\frac{\text{6}}{60}\times100\text{ \%} \end{gathered}[/tex]

After simplification, we have

[tex]\text{percentage change =10\%}[/tex]

Therefore

The percentage increase is 10%
