Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
C.

Answer: 153 trays
Step-by-step explanation:
hotdogs =153

The maximum amount of trays will be determined by the minimum food which is hotdog, so, the hotdog is the constraint.
Mike will have to use 153 trays.
