An adult blue whale can weigh as much as 150 tons.
Let y represent the number of blue whales in all the oceans. Which expression represents the maximum weight in tons of all the whales in the oceans?
A. 150y
B. 150 + y
C. 150/y
D. 150 – y
The correct expression that represents the maximum weight in tons of all the whales in the oceans is A. 150y.
This is because the weight of a single blue whale is 150 tons, and multiplying this weight by the number of blue whales in all the oceans (represented by y) gives us the total weight of all the whales.
