Samantha estimated that she ate cereal for breakfast 80% of the days of the year. Given a year with 365 days, on how many days did Samantha eat cereal that year?

292 days.

Step-by-step explanation:

If Samantha ate cereals for breakfast 80% of the days of the year,

How many days did she eat cereal for breakfast given a year with 365 days.

80/100 * 365

80/100 can be further broken down to the lowest form of 4/5,

So, 4/5 * 365

= (4 * 365) / 5

= 1460/5

= 292 days.

So if Samantha ate cereal for breakfast 80% of the time in a 365 day year, then she ate cereals 292 times for breakfast that year.
