Problem: gary ’ s gas station serves an average of 15 cars per hour on saturdays , 10 cars per hour on sundays , and 9 cars per hour on all other days of the week . if the station is open from 6 a . m . to 10 p . m . every day , how many cars does gary ’ s station serve over the course of a typical week ?
Rationale: 6 a . m . to 10 p . m . = 16 hours number of cars serviced on weekdays = ( 16 * 9 * 5 ) number of cars serviced on saturday = ( 16 * 15 ) number of cars serviced on sunday = ( 16 * 10 ) number of cars served in a week = 16 ( 45 + 15 + 10 ) = 16 * 70 = 1120 answer : a
annotated_formula: floor(divide(multiply(add(6, 10), add(add(15, 10), multiply(9, add(const_4, const_1)))), const_1000))
