Nikki bought a patio set on sale for $390. The original price was $850. (a)
Find the amount of discount.
$ 460
(b)
Find the discount rate (in %). (Round to the nearest tenth of a percent.)

The rate of discount was 43.5%

Step-by-step explanation:

Given,

Original price = $850

Sale price = $480

Amount of discount = Original price - Sale price

Amount of discount = $370

Let,

x be the discount rate.

x% of 850 = 370

Dividing both sides by 8.5

Rounding off to nearest tenth

x = 43.5%

The rate of discount was 43.5%

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
