Question

The difference between the water levels for high and low tide was 3.6 feet. The low is .2 foot. Write an equation to find the water level at high tide.

Answer 1

.2+3.6=3.8 because all you do is add the .2 feet with 3.6 feet

Answer 2

Answer:

$H_{x} = 3.8ft$

Step-by-step explanation:

Thinking process:

Let the problem be expressed like this:

The water level in the high tide be given by: $H_{x}$

The water level in the high tide be given by: $L_{x}$

The difference between the two is given by the equation: $H_{x} -L_{x} = 3.6$

The height in in low tide is 0.2 ft, so the equation becomes:

$H_{x} - 0.2 = 3.6 \\H_{x} = 3.8ft$
