A stock lost 7 1/8 points on Monday and then another 1 7/8 points on Tuesday. On Wednesday, it gained 13 points. What was the net gain or loss of the stock for these three days?

A) a loss of 22 points

B) a gain of 4 points

C) a gain of 18 1/4 points

D)
a gain of 7 3/4 points

Well, looks like this stock is all over the place! Let's break it down. On Monday, it lost 7 1/8 points. On Tuesday, it lost another 1 7/8 points. But on Wednesday, it gained 13 points. So, to find the net gain or loss, we have to subtract the losses and add the gain.

7 1/8 - 1 7/8 + 13 = 12 1/8

So the net gain or loss for these three days is 12 1/8 points. But wait, that's not one of the options! Maybe the stock just wanted to confuse us. Anyway, let's convert it into a mixed number to match the options.

12 1/8 is the same as 12 2/8, which reduces to 12 1/4.

So, the correct answer is C) a gain of 18 1/4 points. Congrats to the stock for making us do some math gymnastics!

To find the net gain or loss of the stock for these three days, we need to add up the changes in the stock's value.

On Monday, the stock lost 7 1/8 points.
On Tuesday, it lost another 1 7/8 points.
On Wednesday, it gained 13 points.

To add or subtract these values, we need to find a common denominator. In this case, we can use 8 as the common denominator.

Now, let's convert the mixed numbers to improper fractions:

7 1/8 = (7 × 8 + 1) / 8 = 57/8
1 7/8 = (1 × 8 + 7) / 8 = 15/8

So, we have:
57/8 - 15/8 + 104/8

Now, let's add the fractions:

57/8 - 15/8 = 42/8
42/8 + 104/8 = 146/8

Now, let's simplify the fraction:

146/8 = 18 2/8

We can simplify 2/8 to 1/4:

18 2/8 = 18 1/4

Therefore, the net gain or loss of the stock for these three days is a gain of 18 1/4 points.

So, the correct answer is:

C) a gain of 18 1/4 points
