Solve the problem.Assuming equal costs, when warehouse workers use hand trucks to load a trailer, it costs the management 
for labor for each trailer. After management purchases a forklift for 
, it costs only 
for labor to load each trailer. Write the equation that models the cost, C(n), of loading n trailers with a hand truck, and the cost, C(n), of loading n trailers with the forklift. Then, solve this system using an algebraic approach.
A. Cost using hand trucks: C(n) = 50n
Cost using forklift: C(n) = 2100 + 25n
n = 82
B. Cost using hand trucks: C(n) = 25n
Cost using forklift: C(n) = 2100 + 50n
n = 82
C. Cost using hand trucks: C(n) = 25n
Cost using forklift: C(n) = 2100 + 50n
n = 84
D. Cost using hand trucks: C(n) = 50n
Cost using forklift: C(n) = 2100 + 25n
n = 84
