To find the number of millions of pet dogs in the United States, we need to multiply the total number of households by the percentage of households that own at least one dog and then multiply it by the average number of dogs per owning household.
First, let's calculate the number of households that own at least one dog:
Number of households that own at least one dog = Total number of households * Percentage of households that own at least one dog
Number of households that own at least one dog = 135 million * 0.365
Number of households that own at least one dog = 49.275 million (rounded to three decimal places)
Next, let's calculate the total number of pet dogs in the United States:
Total number of pet dogs = Number of households that own at least one dog * Average number of dogs per owning household
Total number of pet dogs = 49.275 million * 1.6
Total number of pet dogs = 78.84 million (rounded to two decimal places)
Finally, let's convert the total number of pet dogs into millions by dividing it by one million:
Total number of pet dogs (in millions) = 78.84 million / 1 million
Total number of pet dogs (in millions) = 78.84 million (rounded to the nearest tenth of a million)
Therefore, there were approximately 78.8 million pet dogs in the United States in 2016, rounded to the nearest tenth of a million.
