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

When a price is increased by x percent, we multiply the price by $1 + \frac{x}{100}$.

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

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: $\frac{x}{100}$.

So, after the discount the final price becomes $1890 \times \frac{50}{100} = \frac{1890}{2} = 945$.

Answer 2

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
