I think so cuz I did this and got it right hopefully it is right good luck
X/5 = 24/8
(because the triangles are similar)
x/5 = 3
x = 5*3 = 15 Answer
a/27 = 8/24 = 1/3
a = 9 Answer

C_______M_________Q
|___________________|
21
therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
D: because if you take 9.50-7.50=2 you would get p=price or the price of the pen.
Hope I helped=)
