Answer 2

we are given that

The cost for operating a television varies directly as the number of hours that it is in operation.

It costs $18.00 to operate a standard-size color TV continuously for 30 days.

we have been asked to find how much would it cost to operate the TV for 9 days and 16 hours?

First convert 9 days and 16 hours in days.

9 days and 16 hours
`=9+(16)/(24)=9+ (2)/(3)=(29)/(3)days.`

Since it cost $18.00 for 30 days.

So it will cost
`(18)/(30)= (9)/(15)=(3)/(5)` $ for one day.

So for
`(29)/(3)days.` it will cost
`(3)/(5)*(29)/(3)=(29)/(5)=5.8` $

Hence the required cost is $5.8
