margaret paid $87 for a skirt and a blouse. the skirt costs twice as much as the blouse. what was the cost of the skirt?

To find the cost of the skirt, let's set up an equation.

Let's say the cost of the blouse is "x" dollars.

According to the information given, the skirt costs twice as much as the blouse. So, the cost of the skirt is 2 times "x," which can be written as 2x.

Now, we know that Margaret paid $87 in total for the skirt and blouse. So, we can write the equation as:

x + 2x = 87

Combining the like terms, we have:

3x = 87

To solve for x, we can divide both sides of the equation by 3:

3x/3 = 87/3

Simplifying further, we get:

x = 29

Therefore, the cost of the blouse is $29.

Since the cost of the skirt is twice that of the blouse, the cost of the skirt is 2 * 29 = $58.

So, the cost of the skirt is $58.

s + 0.5s = 87

1.5s = 87

s = 87/1.5

s = ?
