I believe for this question you would subtract how much he spent from how much he sold it for.
This would be 155.00 - (35.00+39.17+36.43).
155.00 - 110.60 = $44.40
Hope this helps!
Answer: 
3026
30

Answer:
<ABC = 27
< BAC = 126
Step-by-step explanation:
<C = <B since it is an isosceles triangle. We know this since AC - AB
<C = 27 so <ABC = 27
The sum of the angles of a triangle = 180
A + B+ C = 180
A + 27+27 = 180
A + 54 =180
A = 180-54
A =126
< BAC = 126
