What is the direct variation equation for the table of ordered pairs? x y 20 24 30 36 40 48

The equation for the direct variation is y = 1.2x

In order to find this, we start with the base for any direct variation equation.

y = kx.

Now we use the ordered pairs to find the value of k to model the equation.

y = kx

24 = k(20)

1.2 = k

Now that we know this, we can model the equation as y = 1.2x and test for the other values --- each of which work in the newly written equation.

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.
