Answer:

Increased by 10.25%

Step-by-step explanation:

[tex]p\%=\dfrac{p}{100}[/tex]

Increased by 5%:

[tex]100\%+5\%=105\%\\\\105\%=\dfrac{105}{100}=1.05\\\\105\%\ of\ x\to1.05x[/tex]

Increased again by 5%:

[tex]105\%\ of\ 1.05x\to1.05\cdot1.05x=1.1025x[/tex]

[tex]1.1025=1.1025\cdot100\%=110.25\%[/tex]

[tex]110.25\%-100\%=10.25\%[/tex]
