Question 760135: Need answer and formula for problem:
Nancy Drew spent 7 & 1/2 hours making phone calls, attending meetings and writing emails. She spent twice as much time attending meetings as making telephone calls, and 1/2 hour longer writing emails than making telephone calls. How many hours did she spend on each task?

let x be the time Nancy spent making phone calls, then we have
x +2x +(x+.5) = 7.5
4x = 7
x = 7/4 = 1.75, 2x = 3.5, x+.5 = 2.25, so
Nancy spent 1.75 hours making phone calls, 3.5 hours attending meetings and 2.25 hours writing emails
