Start at the big tree, and take the instructions
one at a time:
1). Walk 15 west.
2). From there, turn around and walk 2 east.

I mean, let's see some common sense here !
Using algebra to solve for the the cost of the glass lenses gives the value for cost of glass lenses to be 4.
<h3>What is the cost of the glass lenses?</h3>
The cost of the glass lenses is calculated as follows:
Let cost of glass be y
Cost of plastic lenses = 4y
Cost of eye exam and frames be z.
z + y = 30 (i)
z + 4y = 42 (ii)
(ii) - (i)
3y = 12
y = 4
Inconclusion, the cost of the glass lenses is 4.
