Agatha's Photo Place prints photos directly from smartphones. The table shows costs for several different numbers of photos if fewer than one hundred 4×6 photos are ordered. If the number of photos ordered is more than ninety-nine and fewer than two hundred, each photo costs $0.17 and there is a $4.50 shipping fee. If two hundred or more photos are ordered, each photo costs $0.15 and there is no shipping fee. What is the piecewise-defined function that expresses the cost of the order, C(x), in terms of the number of photos ordered, x ?

the answer is a

step-by-step explanation:

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

answer:

a=9
