# The number of U.S. domestic trips, in millions, t years after 1994 can be estimated by p(t) = 8.8t + 954. what do the numbers 8.8 and 954 signify?

I tried this:

#### Explanation:

$954$ will be the initial number (in millions) of trips at, say, $t = 1994$.

$8.8$ will be in millions/year representing the increase of number of trips each year, so that after $1$ year you'll have:

$8.8 \cdot 1 + 954 = 962.8$ millions trips;

and after $2$ years:

$8.8 \cdot 2 + 954 = 971.6$ millions trips;

etc.
