Answer 1

A = 60 divided 2.5
B=24

Answer 2

Sure. The height of the tree is a function of the time in days. Let's call the function h(t) where t is the time in days.

At t=0 we know h(t)=5 centimeters and each day we increase 2.5 centimeters. So our function is

$h(t) = 5 + 2.5 t$

We want to find t when h(t) = 65 so our equation is

$65 = 5 + 2.5 t$

That's the answer for the first box. We solve for t:

$65 -5 = 2.5 t$

$t = (65 - 5)/2.5 = 60/2.5 = 24 \textrm{ days}$
