Luda [366]

Answer:

82.5% Americans owned a TV also owned a DVD player .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

Of the 114.2 million Americans who owned a TV, 94.2 million also owned a DVD player.

Here

Part value = 94.2 million

Total value = 114.2 million

Putting all the values in the formula

$Percentage = \frac{94.2\times 100}{114.2}$

$Percentage = \frac{94200\times 10}{1142\times 10}$

$Percentage = \frac{942000}{11420}$

Percentage = 82.5 %

Therefore 82.5% Americans owned a TV also owned a DVD player .
