Give the step-by-step reasoning process and then the final answer. Austin receives $5 for every hour he helps his father build a deck in their backyard. He works for 2 hours on Mondays, an hour on Wednesdays, and 3 hours on Fridays. If Austin wants to buy a bicycle that costs $180, how many weeks does he have to work?
Austin works a total of 2 + 1 + 3 = 6 hours a week. Since he is paid $5 per hour of work, he'll earn $5 * 6 = 30 in a week. To make $180, he'll have to work for $180 / $30 = 6 weeks.
The final answer: 6.
