Amount the outstanding balance on a particular charge card in 1966 = $156

Amount the outstanding balance on a particular charge card in 2002 = $390

Let the number of year be x

and let the amount of outstanding balance be y

As we know the formula for "Slope ":

Here is the coordinates :(1966,156) and (2002,390)

now, we know the formula for "Equation of line":

Hence, the debt in 1999 is estimated to be 370.5 billions.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
