b. feline flavor has a lower unit price of $1.30/pound.
c. kitty kibbles has a lower unit price of $1.40/pound.
d. kitty kibbles has a lower unit price of $1.30/pound.

D. Kitty Kibbles has a lower unit price of $1.30/pound.

Step-by-step explanation:

Given :

A 16-pound bag of Kitty Kibbles is $20.80.

A 8-pound bag of Feline Flavor is $11.20.

Solution :

Cost of 16 pound bag of Kitty Kibbles =  $20.80.

Cost of 1 pound bag of Kitty Kibbles =    

                                                             = $1.3

Cost of 8 pound bag of Feline Flavor =   $11.20

Cost of 1 pound bag of Feline Flavor =    

                                                             = $1.4

Since cost of 1 pound bag of kitty is less than 1 pound bag of Feline i.e. $1.3<$1.4

Thus,Kitty Kibbles has a lower unit price of $1.30/pound.

Hence Option D is correct .

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
