Online jewelry sales have increased steadily. in 2003, sales were approximately 2 billion dollars, and in 2013 they were approximately 5.5 1 billion. construct a model to predict online jewelery sales. use your model, to find the predicted online jewelry sales for 2015? (express your answer rounded correctly to the nearest tenth of a billion.)

1)

2) 6.4 billion.

Step-by-step explanation:

1) Let the model that is used to find online jewelry sales ( in billions ) after x years,

Let 2003 is the initial year,

That is, for 2003, x = 0,

The sales on 2003 is 2 billion, y = 2,

⇒

Now, in 2013 they were approximately 5.5 1 billion

i.e. if x = 13 then y = 5.51,

With help of graphing calculator,

r = 0.081,

Hence, the model that represents the given scenario is,

2) For 2015, x = 15,

Hence, online jewelry sales for 2015 would be,
