Answer:

$10.

Step-by-step explanation:

Let x represent the original cost of bag of cat food.

We have been given that a pet store owner set the price of a bag of cat food at 50% above the cost. So the cost of cat food would be x plus 50% of x.

x+\frac{50}{100}*x\rightarrow x+0.5x=1.5x

We are further told that the price was reduced by 20%, when it did not sell. So price of cat food after reduction would be 1.5x minus 20 percent of 1.5x.

1.5x-(\frac{20}{100}\times 1.5x)

1.5x-(0.20\times 1.5x)

1.5x-(0.3x)

1.2x

Since price after reduction was $12, so we will equate 1.2x with 12 as:

1.2x=12

\frac{1.2x}{1.2}=\frac{12}{1.2}

x=10

Therefore, the original cost of cat food was $10.

Answer:

To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.
