(3, 5) (6.5, 1.5) (5.5, 2.5) (2.5, 5.5)

Step-by-step explanation:

Given -

Equations

To Find -

Now,

adding both equation, we get -

x + y + x - y = 8 + 3

2x = 11

x = 11/2

Now, substituting the value of x on x + y = 8, we get -

5.5 + y = 8

y = 8 - 5.5

Hence,

(5.5, 2.5) pair of coordinates satisfies both equations.

idk bring the function back   im not smart

step-by-step explanation:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
