Those are 185, 186 and 187
What you do is create this system of equations:
x+y+z=558 (three integers add up to 558)
x+1=y (they are consecutive, so that is translated as a number+1)
y+1=z (same logic as before)
And then you just resolve that system.
The answer is 28.
Check: 28-12= 16
1/4 of 16= 4
3/4 of 16= 12
so Carmen takes 3/4 more time of the trip to the market when she return s home.
