Answer:

Step-by-step explanation:
Let LC be Lake Carl, LS be Lake Susan, and LW be Lake Wayne
First, find a way to denote all the lakes using one lake depth
LC = 1 1/8
LS = 3LC
LW = 3LS or 6LC
Then write an equation.
LW - LS = 6LC - 3LC = 3LC
Substitute LC and calculate.
3 * 1 1/8 = 3 3/8
Hope this helps :)
Have a great day!
