Fred started studying how the number of branches on his tree grows over time. The relationship between the labs time t in years
since Fred started studying the tree in the number of its branches B year(t), is modeled by the following function:
Byear(t)=20•(2.5)^t

This is called a "substitution problem" is where you have variable that have defined values and plug them in value calculate the expression.
B = 3m + 2p # Starting equation
2 = (3)(5) + 2p # Substitution
2 = 15 + 2p # Multiplication
-13 = 2p # Subtract 15 from both sides
= p # Divide both sides from 2
p = # Use the reflexive property of equality
Hope this helps!
