We want to find out how much Sarah paid for her bike. We can use a number line to visualize the given situation. From the exercise, we know that the bike cost $$ 260 .$ Sarah had a coupon that was worth $$ 55$ off the cost of any bike. Let's list the steps we need to follow to create a number line for this situation.

First, we start at $0 .$
Then, we move $260$ units to the right. This represents the initial cost of the bike.
Finally, we move $55$ units to the left to represent Sarah using the coupon.

Let's mark these steps on a number line.

As we can see from the graph, the sum of

260

and

- 55

is located

55

units to the left of

260 .

Let's add the two integers to find out how much Sarah paid for her bike. Consider the expression from the exercise.

260 + (- 55)

Notice that we are adding two integers with different signs, one positive and one negative. This means that we will subtract the absolute values of the integers. Let's take a look.
