Question

a store raises price for a $1,260 phone by 50% and puts a 50% off sign on it. what is the final price of the phone with no tax ?

Answer 1

First price increased 50%

$1,260 + $1,260*50/100 = $1,260 + $630 = $1,890

Then discount 50%

$1,890 - $1,890*50/100 = $1,890 - $945 = $945 This is the final price.

ANSWER final price is $945 without taxes

Answer 2

When a price is increased by x percent, we multiply the price by
`1 + (x)/(100)`.

In this case, the price is $1260 and it increases by 50%. When we put that in an equation:
`1260 * (1 + (50)/(100)) = (1260 * 150)/(100) = 1890`

So, the increased price is $1890.

After that, they applied a discount of 50% to the increased price. To find a decreased price we multiply the price by:
`(x)/(100)`.

So, after the discount the final price becomes
`1890 * (50)/(100) = (1890)/(2) = 945`.
