This is a simple equation. First, We need to read in context. Tucker has already spent 5 minutes on the phone. He also expects to spend 2 more minutes for each phone call he routes.
The Question is asking: How much time will he be spending on the phone if he routes 2 phone calls?
Your equation:
(2×2)+5=?
If we follow PEMDAS, Our equation will look like:
(4)+5=?
Your final answer is 9.
Tucker will spend 9 minutes on the phone in total.
