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.

oksano4ka [1.4K]

Answer:

\frac{1}{6}*\frac{4}{13}

Step-by-step explanation:

A 6 sided die has 6 outcomes.

Your sister picks from a 13 - slice plate meaning the fact that there are 13 outcomes.

There are 4 yellow slices so picking a yellow slice has a \frac{4}{13} chance

You need to mutiply both displayed values to solve this problem.

\frac{1}{6}*\frac{4}{13}

The first gardener can finish the job in 6 hours, and the second gardener can do the same job in 7 hours. How long it will take
marissa [1.9K]

If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.

By the same logic, the second gardener completes 1/7 of the job per hour.

So, if they work together, they complete

\dfrac{1}{6}+\dfrac{1}{7}=\dfrac{7+6}{42}=\dfrac{13}{42}

of the job per hour.

So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is

\dfrac{42}{13}\cdot 60 \approx 194

So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.

Out of 30 questions, Ahmad answer 12 of them incorrectly. What percent of the questions did he answer correctly?
kati45 [8]
First, you would need to determine how many questions he got correct. 
30 - 12 = 18

Next, you would need to create an equation for this problem. Let x represent the unknown percentage. 
\frac{18}{30} = \frac{x}{100}

Now, you would cross multiply. 
30x = 1,800

The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30. 
x = 60

Ahmad got 60% of the questions correct. 

I hope this helps!
