We know the equation for company A is P(t) = 1.8(1.4)ᵗ.
and what we know about company B is that their equation is linear, and we also have 3 months in a table of values, and we can simply use two points from there to get the equation of company B, let's do so using (3,5) and (7, 25),
now, the end of the year will be at the twelfth month, namely t = 12, and the four month well we know that t = 4.
how did each one fare?
so, notice, on the fourth month B did better than A, but at the end of the year, A ended up better off than B.
