Question

A landowner wanted to determine the change in the water levels of his pond over time. First, he filled the pond to a water level of five feet. After two weeks, the water level was at 3.4 feet. If the water level continues to change at that same rate, which of the following statements applies?
A. For each week that passes, the water level decreases by 1.6 feet.

B. For each week that passes, the water level increases by 1.6 feet.

C. For each week that passes, the water level decreases by 0.8 foot.

D. For each week that passes, the water level increases by 0.8 foot.

Answer 1

The answer is c because if you subtract 5-3.4 and get 1.6 then you divide that by two you get .8, and if you subtract point 8 twice for two weeks you get 3.4
