In a country, the first step to obtain a driver's license is the hiring of three products:
- package with 20 theoretical classes;
- package with 10 practical classes;
- vehicle rental for conducting practical classes.
A person who intends to obtain a driver's license researched the value of vehicle rental and the values of each theoretical class and each practical class at three driving schools. The table presents these values.
| Driving School | Value of each theoretical class (R\$) & Value of each practical class (R\$) | Vehicle rental (R\$) |
| I | 10 | 80 | 400 |
| II | 30 | 50 | 200 |
| III | 20 | 40 | 400 |
She will hire the three products at the same driving school so that the total cost in this first stage is as small as possible. The driving school that will be hired is
(A) I, with a total cost of R\$ 1400.00.
(B) II, with a total cost of R\$ 1300.00.
(C) II, with a total cost of R\$ 1300.00.
(D) III, with a total cost of R\$ 1200.00.
(E) III, with a total cost of R\$ 1200.00.
