Nikki brought a patio set on sale for $480 the original price was 850 what is the rate of discount

56 or 55% off depending on rounding up or down

Step-by-step explanation:

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%

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
