Question

On Saturday mornings, Charlie volunteers ate the hospital where his mom works. One Saturday, he answers phone calls at the information desk while the receptionist is away. Then, he spends 20 minutes delivering flowers to patients' rooms. In all, Charlie volunteers at the hospital for 60 minutes that day. Which equation can you use to find the amount of time t, that Charlie answers phone calls?

Answer 1

Answer: t + 20 = 60; 40 minutes are spent answering phone calls.

Step-by-step explanation: We know that 20 minutes are spent out of a 60 minute day of volunteer work. So, with the equation, t + 20 = 60, we can solve to find out that 40 minutes are spent answering phone calls.
