Answer:
Total laps = 10d
Step-by-step explanation:
Let c = Carl's laps
d = Daria's laps
e = Erin's laps
c = 3d
c = e/2
c + d + e = totals laps
We can insert 3d in place of c in the third equation
3d + d + e = total laps
Also, e/2 equals 3d
e/2 = 3d
Multiply both sides by 2
(e/2 = 3d)2
e = 6d
Insert the new e
3d + d + 6d = 10d = totals laps
The answer is 11 because you do the smallest parenthesis. and work your way out.

Find percent increase by subtracting the amounts and dividing it by the old amount, then multiply the result by 100 to make it a percent.
Increase= (277-210)/210
67/210
Then it ends up as 0.319047619...
Multiply that by 100 to make it a percent, which is..
31.9047619..
Round it off, and you get..
32%!
