If you work 12 hours and earn $168, then at what rate, in dollars / hour, were you making money? YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Your solution: ‘$168’ represents the total dollars earned for all hours worked. ‘12’ indicates the total hours worked contributing to the total of $168. The hourly rate of pay in dollars is unknown: a x 12 = $168.
