Barn sells for $1.20 per ounce if this is gargantuan. 8.5 Oz is worth for her Saturday brunch what was her total bill

15,60$

Step-by-step explanation:

1.20x8.5=15.60

If I am not misreading this, the answer is $10.20

Step-by-step explanation:

8.5•1.2= 10.2

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
