Answer 1

D. Begin at 36 and move four units to the left three times.

Explanation:

We have been given an expression and a number line. We are asked to choose the best representation of our expression on number line.

`36-3(4)`

We can see that our point is on 36 on given number line.

We also know that negative numbers are on the left side of the number line and the values of numbers increase to the right on number line.

The meaning of
`3(4)` is 3 times 4.

`36-3(4)` means that we begin at 36 and will move four units to the left three times. Therefore, option D is the correct choice.
