If you mean the price is now 120% of the original, $<span>4.74 (3.95 * 0.8) is the new price.
If you mean the price is now 80% of the original, $3.16 (3.95 * 1.2) is the new price.</span>
(1) y = 7x , (2) y = 11x , (3) y = 9x , (4) y = 28x
given y varies directly as x then y = kx ( k is the constant of variation )
(1) find k using the given conditions k =
=
= 7
equation is y = 7x
(2) k =
= 11
equation is y = 11x
(3) k =
= 9
equation is y = 9x
(4) k =
= 28
equation is y = 28x
