Work Step by Step
One rating point represents 1% of the television market. As there are 115.6 million households, multiply 115.6 million times 1%:
Rating of Household = 0.01 x 115,600,000 = 1,156,000
Now, multiply this number by each of the given C3 Ratings:
Sunday Night Football
C3 Rating x 1,156,000 = 7.9 x 1,156,000 = 9,132,400
Big Band Theory
C3 Rating x 1,156,000 = 5.1 x 1,156,000 = 5,895,600
The Voice
C3 Rating x 1,156,000 = 3.9 x 1,156,000 = 4,508,400
How I Met Your Mother
C3 Rating x 1,156,000 = 3.2 x 1,156,000 = 3,699,200
Agents of S.H.I.E.L.D.
C3 Rating x 1,156,000 = 3.1 x 1,156,000 = 3,583,600
