Question

80% of the doctors surveyed believed exercising 30 minutes a day can help you live a healthier life. If 240 doctors believe in exercising, how many doctors were surveyed?

Answer 1

Answer:

Step-by-step explanation:

The question you should be asking yourself is, "80% of how many doctors is 240?"  Algebraically, 80% is .8, "of" is multiplying, "how many doctors" is our unknown, and "is" means equals.  Putting that all together:

.8x = 240 so

x = 300
