Answer 1

(C)The relationship is multiplicative because the number of gallons can be

found by multiplying the number of minutes by 8.

Explanation:

Given the table below which shows the relationship between the number of minutes that a hose has been on and the number of gallons of water that have been added to a plastic pool.

`\left|\begin{array}c$Minutes Hose On&$Gallons of Water in Pool\\-------&-------\\0&0\\5&40\\10&80\\15&120\\20&160\end{array}\right|`

We can see that if we multiply the first column by 8, we will obtain the second column. Therefore the relationship is multiplicative because the number of gallons can be found by multiplying the number of minutes by 8.

The correct option is C.
