Answer: The debt in 1999 is estimated to be 370.5 billions.
Step-by-step explanation:
Since we have given that
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.
Answer:
a=(d-c)/b
Step-by-step explanation:
Subtract c from both sides:
ab+c−c=d−c
∴ab=d−c
Divide both sides by b
ab/b=d−c/b
so the answer is... a=(d-c)/b
