While pricing the preliminaries, a contractor determines that they will require the use of a mobile crane for $14$ working days. The contractor secures quotes from the only two plant suppliers in the area and compares them to determine which will be more cost effective.

Supplier $1$ charges a flat rate of R$10,000$ for the hiring of the crane and an additional R$2,500$ per day for the continued use of the crane. A full day is required for each establishment and disestablishment of the crane.

Supplier $2$ charges a rate of R$3,500$ per day for the hiring of a mobile crane that does not need to be assembled or disassembled.
