**Example 1 – page 139: #53**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? Steps for Solving Application Problems Step 1: Define the variable. Let d = maximum depth in 1999 Step 2: Draw and label a picture, if necessary. Step 3: Write an equation. Depth in 1999 - 9.9 feet = depth in 2004 Step 4: Solve the equation. Step 5: Write a complete sentence that answers the question in the problem. The maximum depth of the Dead Sea in 1999 was 1046.6 feet.**Example 2 – page 139: #55**A rectangular trampoline has a area of 187 square feet. The length of the trampoline is 17 feet. What is its width? Steps for Solving Application Problems Let w = width of the trampoline Step 1: Define the variable. l = 17 ft Step 2: Draw and label a picture, if necessary. w Step 3: Write an equation. Area = length X width Step 4: Solve the equation. Step 5: Write a complete sentence that answers the question in the problem. The width of the trampoline is 11 feet.**Practice 1 – page 139: #56**The van used to transport patients to and from a rehabilitation facility is equipped with a wheelchair lift.
