The function D(t) = 398 + 5340 can be used to approximate the total average credit card debt in a U. S. household (in dollars) t years after 1995. Use this function to predict what the total average credit card debt will be in the year
2018.

In the year 2018, the total average credit card debt for a U. S. household will be $

10 b/c 5*2 =10

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

inverse operation of addition

the correct answer is c) 2.
