Answer:
300
Step-by-step explanation:
Let's call N the total number of televisions. We have that 240 televisions make up of 80% of the total number of televisions, so we can rewrite it as
[tex]0.80 N = 240[/tex]
where 0.80 means 80 % ([tex]\frac{80}{100}=0.8[/tex]. By solving the equation above, we find
[tex]N=\frac{240}{0.80}=300[/tex]
So, the total number of televisions is 300.
