Question

Can you help with this?

Answer 1

from 1985 to 1998 is 13, so just plug 13 into the x

y= 312.5(13) +156.25
y = 4218.75

4218 bald eagle pairs have been sold in 1998

Answer 2

1998 is 13 years since 1985 so you plug 13 into the equation as your x and then solve:

y = 312.5(13) + 1562.5
y = 4062.5 + 1562.5
y = 5625
Your answer is 5625 bald eagle pairs.
