Answer 2

Answer:

Step-by-step explanation:

Taking the variable A to be the percentage of households

that had cordless phone in 2000, we can set up the equation:

A + (12.9%) A = 86%

where to convert percentage to decimal, divide by 100:

A + 0.129 A = 0.86

Calculating for A:

1.129 A = 0.86

A = 0.86 / 1.129

A = 0.7617

or

A = 76.17%

 

So around 76.17% in 2000.
