Tickets to the planetarium cost $5.25 each and come in a book of 8 how much change will kenny get a $60 fee buys a book of eight

$ 18.00

Step-by-step explanation:

$5.25 x8 = $42.00

$60.00 - 42.00 = $18.00

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
