To determine the increase in television ownership between 1951 and 1963, we need to look at both the number of televisions owned and the percentage of households owning televisions in those years.
Firstly, let's examine the number of televisions owned:
- In 1951, the number of televisions owned was [tex]\(10,320,000\)[/tex].
- In 1963, the number of televisions owned was [tex]\(50,300,000\)[/tex].
To find the increase in the number of televisions owned, we subtract the number in 1951 from the number in 1963:
[tex]\[ \text{Increase in number of televisions} = 50,300,000 - 10,320,000 \][/tex]
Carrying out the subtraction:
[tex]\[ 50,300,000 - 10,320,000 = 39,980,000 \][/tex]
Thus, the increase in the number of televisions owned from 1951 to 1963 is [tex]\(39,980,000\)[/tex].
Next, let's look at the percentage of households owning televisions:
- In 1951, the percentage of households owning televisions was [tex]\(23.5\%\)[/tex].
- In 1963, the percentage of households owning televisions was [tex]\(91.3\%\)[/tex].
To find the increase in the percentage, we subtract the percentage in 1951 from the percentage in 1963:
[tex]\[ \text{Increase in percentage} = 91.3\% - 23.5\% \][/tex]
Carrying out the subtraction:
[tex]\[ 91.3\% - 23.5\% = 67.8\% \][/tex]
So, the increase in the percentage of households owning televisions from 1951 to 1963 is [tex]\(67.8\%\)[/tex].
In summary, between 1951 and 1963:
- The number of televisions owned increased by [tex]\(39,980,000\)[/tex].
- The percentage of households owning televisions increased by [tex]\(67.8\%\)[/tex].
