A number of light bulbs were purchased to illuminate a gym. However, only of them were needed and 160 leftover light bulbs were returned. If only 60% percent of their cost, or \$96, was reimbursed, how much money was spent on illuminating the gym?

160
320
360
372
384

$$1/3$$ x = 160
x=480
x=total number of bulbs

60% is the cost of total cost of bulbs or cost of 160 leftover bulbs.
