$270 equals 135% of the original price

270/x=135/100

135*2=270
100*2=200

Final answer: $200

Answer : The original price of dress was, $200.00

Step-by-step explanation :

Let the original price be, 'x'

So, the selling price will be = x+35\% \times x

The selling price of dress = $270.00

Now we have to calculate the original price of the dress.

x+35\% \times x=270.00

x+\frac{35}{100} \times x=270.00

\frac{135x}{100}=270.00

x=\frac{100}{135}\times 270.00

x=200.00

Thus, the original price of dress was, $200.00

So it seems as if the first problem is asking this:

2 \frac{1}{6} - \frac{11}{15}x. 

If x=0.15, then 11/15*(0.15) is 0.11 or 11/100. 

The second problem is asking:

\frac{x}{4} + \frac{1}{2} = \frac{x}{3} + \frac{1}{6}

To solve algebraically, you want to get rid of the denominators under the x's. To do so, you want to multiply by the Least Common Multiple (LCM) of the denominators. For 3 and 4, the LCM is 12. Multiply everything by 12 to get:

3x+6=4x+2

Now, solve for x

Subtract 4x from both sides:
-x+6=2

Subtract 6 from both sides:
-x=-4

Multiply by -1 on both sides:
x=4.

Fertilizer is sold in 100 pound bags labelled with the amount of nitrogen ( N), phosphoric acid ( P2O5), and potash ( K2O) prese
Grace [21]

Answer:

For Vigoro are needed

2929*35.8479 ≅ 104,988.49 (N)

33*3.4351≅113.35 (A)

44*31.2181≅1373.59 (P)

For Parkera are needed

1818*35.8479≅65,171.48 (N)

2525*3.4351≅8673.62 (A)

66*31.2181≅2060.39 (P)

Step-by-step explanation:

we have that in every 100100 pounds of compound nitrogen (N), phosphoric acid (A) and potash (P) are present and that according to the product brand the concentrations vary, therefore:

For Vigoro

2929 N, 33 A, 44 P

For Parkeras

1818 N, 2525 A, 66 P

Now, we need 170170 N, 8787 A and 3434 P of final product containing the components of the types of fertilizers

You can see that the compounds are the same what changes are the proportions from there that

2929N+1818N=170170 ⇒ 4747N=170170 ⇒ N=170170/4747 ≅ 35.8479

33A+2525A=8787 ⇒ 2558A=8787 ⇒ A=8787/2558  ≅ 3.4351

44P+66P = 3434 ⇒ 110P=3434 ⇒ P=3434/110 ≅ 31.2181

Finally

For Vigoro are needed

2929*35.8479 ≅ 104,988.49 (N)

33*3.4351≅113.35 (A)

44*31.2181≅1373.59 (P)

For Parkera are needed

1818*35.8479≅65,171.48 (N)

2525*3.4351≅8673.62 (A)

66*31.2181≅2060.39 (P)
