An electronics store buys 100 smart light bulbs at $25 each. After 6 months, 15% are defective and returned at full price, while the rest are sold at a 40% markup. If 5% of the total were later stolen and not recovered, how much revenue is generated from sales?

**Why Smart Retailers Are Close-Valued on Efficiency — and What It Means for Smart Home Lights** Have you ever wondered how much a smart lighting purchase really pays off — especially when unexpected costs like returns and theft factor in? For retailers managing high-value tech inventory, this scenario is more common than it sounds: buying 100 smart light bulbs at $25 each, then facing quality issues, markups, and loss. Recent trends show electronics buyers are increasingly balancing profitability with risk — turning what seems like a simple inventory decision into a financial puzzle. This form of consumer and retail analysis is gaining attention, especially as smart home adoption grows across the U.S. The scenario: an electronics retailer purchases 100 smart lighting bulbs at $25 each, totaling $2,500. Six months in, 15%—or 15 bulbs—fail quality checks and must be returned fully charged and refunded. Of the remaining 85 bulbs (85 units), a 40% markup boosts each sale price to $35. But while revenue rises, 5% of the full batch—5 bulbs—goes missing and is never recovered. This thin but meaningful loss reshapes the final financial picture. Breaking it down simply: 85 bulbs sold at $35 each generate $2,975. Subtracting the $1,500 cost of the original stock, the immediate profit is $1,475. However, the 5 missing units represent $125 in untraceable sales—reducing final revenue to $2,850. This difference highlights how even small loss rates compound in retail, especially with high-value smart devices prone to quality variances.
