Question

A researcher determined the amount of ducks that were in a pond over a four-year time span. The results are shown in the table below.

Year Ducks
1 64
2 78
3 92
4 106

Select an equation that best models the amount of ducks (d) that will be in the pond during the nth year.

Answer 1

Every year there are 14 more ducks. The starting point would be 50 and the equation is:

d = 14*year+50
