Question

Salinity is a measure of the salt content of a body of water. One researcher measures the salinity of the Indian Ocean as 3.2%. Another researcher measures the salinity of the Dead Sea as 34%. A bucket of water from the Indian Ocean contains 56 grams of salt. How much salt is contained in the same amount of water from the Dead Sea? How many grams?
Justify your answer

Answer 1

Divide each percentage to find a multiplier:

34/3.2 = 10.625

The Dead Sea is 10.625 times saltier than the Indian Ocean.

So if Indian Ocean bucket = 56 grams of salt

Multiply that by our multiplier.

56 * 10.625 = 595 grams

The answer is 595 grams

Answer 2

88 because you add then multiply
