The probability that equipment used in a hospital lab will need recalibration is given in the following table. A service firm is willing to perform maintenance and do any necessary calibrations for a fee of $$525$ per month. Recalibration costs $$325$ per time. $($Round the answer of "Expected cost of recalibration" to nearest whole number.$)$

Number of Recalibrations $01234$

Probability of Occurrence $\mathrm{.}10\mathrm{.}30\mathrm{.}30\mathrm{.}20\mathrm{.}10$
