32 pages of advertisement.

Step-by-step explanation:

Assuming the advertisements are published at the same rate as the average, the rate is 384/960 = 2/5

So out of 80 pages, we can expect

80*2/5 = 32 pages of advertisement.

i think it might be a but you might want a second opinion

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
