Count the number of hexagons and smiley faces to create the ratio
hexagons : smiley faces = 3 : 4 ← in simplest form
Multiply each part of the ratio by 2 and 3 gives

Using the rule of radicals
×
⇔
Simplifying each radical before combining them.
=
= ×
= 3
-----------------------------------------------------------------------------
=
= ×
= 5
---------------------------------------------------------------------------
Hence
2(3) - 3(5
= 6 - 15
= - 9 → C
is simply the difference of both numbers of course, the price it was sold minus the price it was bought at.
