Answer:

a: 45+(25xb)=n

b: 170=n

c: 120=n (took 3 hours)

Explanation:

a:45+(25xb)=n

b:45+(25x5)=n

45+(125)=n

45+125=n

170=n

c:45+(25xb)=n

120-45=75

75/25=3

45+(25x3)=n

45+75=n

120=n

Answer:

it would end up being 170 dollars. because if they were there for 5 hours at 25 dollars an hour and they are charging a service fee of 45 dollars, then you add it all up and boom you got ur answer. and part 2 would be they worked three hours plus the 45 dollar fee.
