1. ## Last one I swear - word problem!

In 1990, the number of births per 1000 people in the United States was 16.7 and decreasing at 0.26 birth per 1000 people each year. Write a function and use it to estimate the number of births per 1000 people in 2010.

Help, I have no idea with this one!

2. Try $y = 16.7\times 0.74^x$

3. Thank you!
