Approximately 45 of U.S. homeowners have a cell phone. What percent of homeowners do not have a cell phone? A 45%
B 20%
C 80%
D 55%

D 55%

Step-by-step explanation:

I am assuming that the "45" is 45$ so then we do 100%-45$=55% But, if the "45" is 1 in 45, then the answer is 1-1/45=44/45 which rounds to 98%. That isn't any of the answers, so should be 55%
