Hi boomgoesthegmat,

This question is really just about pulling the relevant information from the chart and doing the basic arithmetic to answer the question that's asked.

We're asked to choose the answer that closest to the DIFFERENCE between the highest tide and lowest tide in the table.

Highest Tide: 2.2 ft
Lowest Tide: -0.5 ft

Difference = (2.2) - (-0.5) = 2.7 ft

Final Answer: E

From the graph, we can see the following information:

Highest tide at 11:30 AM = 2.2 ft
Lowest tide at 6:00 PM = - 0.5 ft

Difference = 2.2 - (-0.5) = 2.7 ft

Correct Option: E

We are given a graph in which the y-axis displays the height of the tide. We must determine the difference between the heights of the highest and lowest tides.

highest tide = 2.2 feet

lowest tide = -0.5 feet

Thus, the difference between the heights is 2.2 - (-0.5) = 2.2 + 0.5 = 2.7 feet.

Answer: E
