Question

Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(m) as a function of months m.

Answer 1

Let
HA(m) = the height of species A as a function of months m
HB(m) = the height of species B as a function of months m

Assuming that the growth rate of the plants is a linear relationship all throughout the growth stages, we have:
HA(m) = 25 + 3m
and
HB(m) = 10 + 8m
