Answer:
$94.81
Step-by-step explanation:
the selling price (before discount 20%) =
$98.60 ÷ (100-20)%
= $98.60 ÷ 0.8 = $123.25
the store paid for the clarinet =
$123.25 ÷ (100+30)%
= $123.25 ÷ 1.3 = $ 94.81
For two line segments to be parallel, their slopes must be equal.
Therefore slope of AB must be equal to slope of CD
which is, option 3
(y4-y3)/(x4-x3)=(y2-y1)/(x2-x1)
