Chapter 0.3, Problem 71E

Health care expenditures The national health care expenditure $H$

(in billions of dollars) can be modeled (that is, accurately approximated) by the formula

$H=738.1{\left(1.065\right)}^t$ where $t$ is the number of years past $1990$

(Source: U.S. Department of Health and Human Services).

What t-value corresponds to $2000$?

Approximate the national health care expenditure in $2000$.

Approximate the national health care expenditure in $2010$.

Estimate the national health care expenditure in $2018$.
