An internet cafe charges 2.75 to use a computer and 0.35 per minute while accessing the internet what is the cost of using the internet for 28 minutes

So you first pay 2.75 to use the computer

then you have to pay for the internet which you used for 28 minutes

28 at 0.35 a minute is 9.8

so 2.75 for the computer plus 9.8 for the internet is

12.55
