Question

The cost of renting a car is $125 a day. Write a function for the situation where d represents the number of days. cd = 125d + 125 / 24d c(d) = 125[d + 1] c(d) = [125d if [[d]] = d 125[[d + 1]] if [[d]]

Explanation / Answer

SOLUTION ---->   Choice( C) EXPLANATION: Cars are rented based on number of days or fraction thereof. Thus, (3 days) would be charged {3*$125}, but (3.2 days) would be charged {4*$125}. Notation "[[ ]]" signifies the integer portion of its argument. Hence, if {d = [[ d ]]}, charge amount should be {d*$125}.   However, if {d > [[ d ]]}, then extra day is charged so total amount would be {[[ d + 1 ]]*$125}. Choice(C) is the correct response. .
