Tran has made a plan to help him study for his math exam. He has broken the material into two parts: part A and part B. He has only 2 hours over the course of the next week to study, and wants to spend twice as much time studying for part A as for part B.

1. What are the restrictions?
2. State 2 constraints from this problem

A+B ≤ 2

A = 2B
A>0
B>0

1. The restrictions in this problem are that Tran has a total study time of 2 hours over the next week, and he wants to allocate his study time in a specific ratio between part A and part B.

2. Two constraints from this problem are:
a) Tran must allocate his study time in such a way that he spends twice as much time studying part A as he does studying part B.
b) Tran's total study time cannot exceed 2 hours in the next week.
