Question 958318
Jon, Denny, and Ashley are taking turns washing cars at a basketball team fundraiser. Together they work for 54 minutes. Jon worked for 15 minutes. Ashley worked twice as long as Denny. How long did Ashley work for? I have taken 54 and subtracted 15 that Jon worked. It left 39 minutes I'm not sure how to finish the rest of this problem

let x be the time Denny worked
let 2x be the time Ashley worked

15 + x + 2x = 54
3x = 39
x = 13

Therefore Denny worked 13 minutes and Ashley worked 26 minutes

Or

39 minutes = Denny's time + Ashley's time (2 times of Denny's)
Denny = 1/3 of the 39 minutes = 13 minutes
Asley = 2/3 of the 39 minutes or 13 minutes*2 = 26 minutes
