Question

If a TV cost $3960.00 and toes on sale during the following week with a 25% discount, what will be the total cost of the TV? but first , round the cost to the nearest ten before taking the discount.

Answer 1

we have the price of TV is $3960.if we round off to the nearest tens we get same 3960 because we have 0 at the end which means lesser than 5 so 60 will be the nearest ten.

discount =
`(25)/(100) *3960=990`

so $990 will be the discount.

and the cost of TV after discount is
`3960-990=$2970`
