x^2+8x+16=0
(x+4)^2+9=0
(x+4)^2= -9

lana66690 [7]

Answer: The total price of a bench is 1.008x.

Step-by-step explanation:

Since we have given that

Let the cost price be 'x'.

Mark up % = 120%

So, Mark up value would be

\dfrac{120}{100}x\\\\=1.20x

Discount % = 20%

Amount of discount is given by

\dfrac{20}{100}\times 1.2x\\\\=0.2\times 1.2x\\\\=0.24x

So, it becomes,

Amount after discount is given by

1.2x-0.24x\\\\=0.96x

Sales tax = 5%

Amount of sales tax would be

\dfrac{100+5}{100}\times 0.96x\\\\=\dfrac{105}{100}\times 0.96x\\\\=1.05\times 0.96x\\\\=1.008x

Hence, the total price of a bench is 1.008x.
