A three pack of bar soap had a wholesale cost of $1.15. A pharmacy wants to sell this product with a markup of 60%. What are the

Svetllana [295]

To find the percentage of something, simply multiply the percentage (converted into a decimal) and the total. 60% = 0.6. 0.6*1.15 = 0.69.
The markup is $0.69.
To find the retail price, add the markup to the wholesale cost. 0.69+1.15= 1.84.
The retail price is $1.84.
Hope that helped you.

For more than three times a number is greater than 22

TiliK225 [7]

Answer:

Four more than three times a number is greater than twenty-two.What is the number?

The number is greater than 6.

Step-by-step explanation:

Given:

Four more than three times a number is twenty-two.

Let the number be 'x'.

Three times of 'x' = '3x'

Four more means further four is added.

So,

The number is $3x+4$

According to the question.

⇒ $3x+4=22$

⇒ $3x+4-4=22-4$ ...Subtracting 4 on both sides

⇒ $3x=18$

⇒ $x=\frac{18}{3}=6$ ...Dividing 6 on both sides

Now if it says that it is greater than 22 then we will use $>$ sign.

So the number is greater than 6 'x' > 6.

Two pipes are used to fill a 300-gallon tub with water. The wide pipe can fill the tub in x hours. The narrow pipe can fill the

Hoochie [10]

Answer:

$\frac{6}{x}-\frac{7}{y}=\frac{7}{12}$

Step-by-step explanation:

#We know that the filling taps will run for a cumulative 4hrs each while the draining hole will empty for a combined 7hrs.

Let x be the rate of the first filling tap, and 2x of the 2nd filling tap and y be the rate of the hole.

#The rate at which the tub fills per hour is :

$V_{tub}=\frac{1}{x}+\frac{1}{2x}-\frac{1}{y}\\\\=\frac{1}{x}(1+\frac{1}{2})-\frac{1}{y}\\\\=\frac{3}{2x}-\frac{1}{y}$

#The volume of the tub at the instant moment the leak is repaired is expressed as:

$V_{tub}=\frac{3}{2x}t_1-\frac{1}{y}t_2=\frac{7}{12}, \ \ \ \ \ \ t_1=4,t_2=7\\\\\\\frac{3}{2x}\times 4-\frac{1}{y}\times7\frac{7}{12}\\\\\\\frac{6}{x}-\frac{7}{y}=\frac{7}{12}$

Hence, the volume of the tub after the leak is repaired is expressed as $\frac{6}{x}-\frac{7}{y}=\frac{7}{12}$
