The function D(t)D(t) can be used to approximate the total average credit card debt in a U.S. household (in thousands of dollars) tt years after 1995.

Interpret the meaning of the statement: D(30)=18.9D(30)=18.9.

I suspect this should be:

"The function D(t) can be used to approximate the total average credit card debt in a U.S. household (in thousands of dollars) t years after 1995.

Interpret the meaning of the statement: D(30)=18.9
"

D(30) = 18.9 then means that the average credit card debt in a US household in the year 2025 (i.e. 1995 + 30) will be \$18900.

That statement makes no sense to me at all.  Are you sure you copied it down correctly?
