For the period 1999-2004, the maximum depth of the dead sea decreased by 9.9 feet. the maximum depth in 2004 was 1036.7 feet. what was the maximum depth in 1999?

Hello,

If the maximum depth in 2004 was 1036.7 feet, which is 9.9 less than in 1999, we can simply add 1036.7 and 9.9 to get the maximum depth in 1999.

Doing this, we have:
1036.7 + 9.9 = 1046.6 

The maximum depth in 1999 in 1046.6 feet. 

Hope this helps!
