The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:

or

By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X.
For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
Answer:
the answer is 672
Step-by-step explanation:
420 × 60% = 252
420 + 252=672
625 is the total number of learners
I mean it depends what lake and where and the temperature, all variables you have to consider.
