Answer:
the current plan will have fewer commercials
Step-by-step explanation:
Given:
Commercials time = 13 minutes
Actual show time = 47 minutes
Therefore,
The ratio of commercial to actual show = [tex]\frac{\textup{13}}{\textup{47}}[/tex]
Now,
The proposed ratio of commercial to actual show = 3 : 7
Therefore,
Proposed time for the commercials per hour = [tex]\frac{\textup{3}}{\textup{3 + 7}}\times60[/tex]
or
= 18 minutes
therefore,
proposed time for actual show = 60 - 18 = 42 minutes
==================================================================
                  Advertisement per hour     Actual show per hour
Current plan               13 minutes              47 minutes
proposed plan             18 minutes              42 minutes
==================================================================
Hence,
the current plan will have fewer commercials
Answer:
the old scheme has fewer commercials for viewers watching 2 hours of TV.
Step-by-step explanation:
Given: Commercials time for every 1 hour = 13 minutes
Actual show time = 47 minutes
So, the ratio of commercial to actual show is 13: 47
The new proposed ratio of commercial to actual show = 3 : 7
Total = 3+ 7 = 10
Now let's divide 60 minutes by 10, we get
60 ÷ 10 = 6 minutes
The new proposed commercials time for every 1 hour = 3 × 6 = 18 minutes
The new proposed actual show time for every 1 hour = 7 × 6 = 42 minutes
Now let's make table .
                 Commercial        Actual show
Old scheme          13 mins             47 mins
New scheme          18 mins             42 mins
For 2 hours program
                  Commercial        Actual show
Old scheme          26 mins             94 mins
New scheme          36 mins             84 mins
So, the old scheme has fewer commercials for viewers watching 2 hours of TV.
