Answer 2

`\$ 2.70* 10^(12)`

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} * amount\ spent\ per\ person\ on\ healthcare}`

=
`8754* 3.09* 10^(8) = 27049.96* 10^(8)`

=
`\$ 2.705* 10^(12)` ≅
`\$ 2.70* 10^(12)`

∴ In 2010, U.S will spend
`\$ 2.70* 10^(12)` on health care.
