Step-by-step explanation:
A) The bus rental would be the total cost or "C". So 700=250+3m.
B) Solve with properties of equality:
700 - 250 = 250 + 3m - 250
450 = 3m
450/3 = 3m/3
150 = m
150 miles
C) Check your answer by plugging the answer into the original equation:
C = 250 + 3(150)
C = 250 + 450
C = 700
