A. \(P(h)=238-10h\)
B. \(P(h)=72-10h\)
C. \(P(h)=68h-150\)
D. \(P(h)=78h-160\)
E. \(P(h)=-160h+78\)

Cost of renting a table = $150
Cost of paying assistant = $10 per hour
Sales = $78 per hour

Assuming no other cost
Profit per hour = sales -total costs
=78h - ( 150 + 10h )
=78h - 150 - 10h
=68h - 150

Answer = c

His fixed cost = $150

P(h)= earnings - cost(fixed + variable)
P(h)=78h - (150 + 10h)
P(h)=68h-150
