A new shirt is usually priced at $63.08.
But Jenny bought it when it was marked
25% off. How much did Jenny pay for it?

Help pleas ?

Jenny paid $47.31 on the shirt

Step-by-step explanation:

$63.08 × 25%

$63.08 × 0.25 = $15.77

$63.08 - $15.77 = $47.31

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
