Question

During a 5 year period 35% of snowstorms in a certain city caused power outages. 39 of the snowstorms did not cause power outages Find the total number of snowstorms in this city over the 5-year period

Answer 1

60

Explanation:

There were x number of snowstorms. Some caused power outages and others did not. 35% of x caused outages. 100% - 35% = 65%. 65% of x did not cause outages. 39 storms did not cause outages, so 65% of x equals 39.

65% * x = 39

0.65x = 39

x = 39/0.65

x = 60
