322 - 299 = 23 people different
23/322 = 0.0714
*100
=7.14% change

You need to solve 322 * x/100 = 299 as this is how you would calculate the discount if you had the original price and the percentage discount.
So 322 * x/100 = 299
x/100 = 299/322 = 0.929
x = 0.929 x 100 = 92.9%
But this the percentage of the original price, just take this away from 100% and you have your answer:
7.1%

area of Rectangle = length x Width A = L x W length is 4 inches greater beneficial than Width: L = W + 4 replace this into the area equation to get: A = L x W A = (W + 4) x W A = W^2 + 4W however the area is ninety six: ninety six = W^2 + 4W Rewrite as: 0 = W^2 + 4W - ninety six that's now a quadratic equation which we could desire to unravel: 0 = (W + 12)(W - 8) W = -12 or W = 8 yet width W won't be in a position to be detrimental, so it is going to equivalent 8. If W = 8, then L = ? L = W + 4 L = 8 + 4 = 12 examine your artwork: A = L x W A = 12 x 8 A = ninety six

to figure the discount on the TV:
299 being the discount price - and assuming a 20% discount
so 299 is 80% of the original price
the equation is 299/n = 80/100
cross multiply to get 80n=29900
divide both sides by 80 to get
the original price, n, was 373.75

Take 299 and divided is by 322. Muliply by 100. Subtract that answer from 100 and you have your percent. It is 7.1%.

I agree with Mark W.

Divide 299 by 322 to obtain percent
299 / 322 = 0.92851429
1 - 0.92851429 = 0.071428571
Multiply the decimal 0.071428571 by 100 to obtain %
0.071428571 X 100 = 7.142857143 %
The answer is 7.14 % rounded to two decimal places.

p = (322-299)*100/322
p = 2300/322
p= 7.143 %
