Abike was recently marked down $200.00 from its initial price. if you have a coupon for an additional 30% off after the markdown, how much will the bike cost if it was originally $950.00?

The bike will cost $525

Step-by-step explanation:

original cost of bike= $950

marked price  of bike= $ (950-200)

                                  = $750

we get an additional 30% off on marked price

so, the bike will cost 70% of 750

                             =

                             = $525

hence, the bike will cost $525

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
