# An average car engine can produce about 100 horsepower. How many 100-watt light bulbs does it take to use the same amount of power?

745

#### Explanation:

So 100 hp = $74570 \text{W}$
Since each bulb consumes $100 \text{W}$ of power the number of lightbulbs the engine could power $= \frac{74570}{100} = 745.7$
