Question 1047025
They match up the way they are listed...
1a, 2b, 3c, 4d
If you look at the factor that each 1.7 or 250 gets multiplied by you can see that the numbers either grow or decay...
I'm thinking the x's should be exponents, corresponding to the years of growth...
For example, look at #3...
{{{y = 250(1.08)^x}}}
tells me that the 250 grows .08 or 8% more than once each year...
