In 1977 Total health expenditure was approx $$47$$ billion.
From per capita graph for health expenditure we know that per capita health expenditure for 1977 was approximately $$240$$

Hence from the information we can form a equation to solve for population during 1977 i.e. $$\frac{47*1000000000}{x}$$ = $$240$$
x = 195833333 = approximately 195 million.
