Answer:

The percent charge of Kanna's DS is 50%

Step-by-step explanation:

we know that

A Nintendo DS takes 4 hours to charge fully (100%)

4 hours is the same that 240 minutes

using proportion

Find out what percentage represent 108 minutes

[tex]\frac{100}{240}\ \frac{\%}{min} =\frac{x}{108}\ \frac{\%}{min}\\\\x=100(108)/240\\\\x=45\%[/tex]

Remember that

Kanna Kamui charge her DS from 5%

so

[tex]5\%+45\%=50\%[/tex]

therefore

The percent charge of Kanna's DS is 50%
