Answer:
C(p) = p*100+300
Step-by-step explanation:
Let
A= cost of labor and material
B= cost of renting the building and equipment
p = no of phones produced per day
C(p) = Total cost in dollars
On forming the equation we are given A but not B so we will find that using the equation
C(p) = p*100+B
and we are given that cost of producing 3 phone will be $600
C(p) = 3*100 + B= 600
B = $300
so the final equation will be
C(p) = p*100 + 300
