Answer:

87 years

Step-by-step explanation:

To find the total age 9 years ago you would subtract 9 from Charles's age only, 19. His grandfather is still always going to be 67 years older than he.

19 - 9 = 10

Add 10 and 67 together to find his grandfather's age back then.

10 + 67 = 77

Now add 10 and 77 together.

10 + 77 = 87

The total age 9 years ago was 87 years.

Today: x=19
y=67+19=86

9 years ago: x=19-9=10
y=86-9=77

The total age 9 years ago: x+y=10+77=87

Answer: ln ( 40) *100

140 = 100 + e^(.01q)

40 = e^(.01q)

Take the natural log of bot hsides

ln ( 40) = .01q

q= ln ( 40 ) * 100
