Answer 1

Answer:

$\ 2.70\times 10^{12}$

Step-by-step explanation:

Complete question is here: In 2010, the population in the United States will be about 3.09x10^8. Spending for health care will be  about $8754 per person. About how much will the US spend on health care in 2010? Write in scientific  notation and round to the nearest hundred.

Given: Per person expenditure on healthcare is $8754.

          Total population in 2010 is 3.09x10^8.

Now, lets find out total money U.S will spend on health care.

$\textrm{Total population} \times amount\ spent\ per\ person\ on\ healthcare}$

= $8754\times 3.09\times 10^{8} = 27049.96\times 10^{8}$

= $\ 2.705\times 10^{12}$ ≅ $\ 2.70\times 10^{12}$

∴ In 2010, U.S will spend $\ 2.70\times 10^{12}$ on health care.
