Elena makes more money for making 10 calls than Diego makes for washing 10 windows.

Diego makes more money for washing each window than Elena makes for making each call.

Elena makes the same amount of money for 20 calls as Diego makes for 18 windows.

Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls.

The equation y=9/10x, where y is the number of dollars and x is number of windows, represents Diego's situation.

The equation y=x, where y is the number of dollars and x is the number calls, represents Elena's situation.
