This week, Emmett's family watched 15.6 hours of TV. That is 60.4% more hours than they watched last week. How many hours of TV did Emmett's family watch then? Round your answer to the nearest tenth.

Answer 1

Emmett's family watched approximately 6.2 hours of TV last week.

Step-by-step explanation:

To find out how many hours of TV Emmett's family watched last week, we need to first calculate 60.4% of the total 15.6 hours they watched this week.

We can do this by multiplying 15.6 by 0.604, which equals 9.4224. To find the number of hours they watched last week, we subtract this value from 15.6.

Therefore, Emmett's family watched approximately 15.6 - 9.4224 = 6.1776 hours of TV last week.
