Hoi Chong Transport, Limited, operates a fleet of delivery trucks in Singapore. The company has determined that if a truck is driven $162,000$ kilometers during a year, the average operating cost is $13\mathrm{.}2$ cents per kilometer. If a truck is driven only $108,000$ kilometers during a year, the average operating cost increases to $16\mathrm{.}6$ cents per kilometer.

Required:

Using the high$-$low method, estimate the variable operating cost per kilometer and the annual fixed operating cost associated with the fleet of trucks.

Express the variable and fixed costs in the form $Y=a+bx.$
