The price of a video gaming system was $259. The price decreased to $199. What is the percent decrease in the price of this system? Round your answer to the nearest whole percentage.

The percentage decrease is 23%

Step-by-step explanation:

Initial price is $259

Final price is $199

Decrease = $259 - $199

= 60

Percentage decrease will be decrease over Initial price multiply by 100%

(60/259) × 100%

= 23.166

≈ 23% to the nearest whole number

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)
