Answer:

$643.50

Step-by-step explanation:

Let i be the profit realized from the sale and d be the discount made on the sale:

#John's selling price can be calculated by first adding profit, i to $450, the d to the new price as:

P_n=P_o(1+i)+d[P_o(1+i)]\\=450(1+0.3)+0.1[450(1+0.3)]\\\\\\=450\times 1.3+0.1(450\times1.3)\\\\=585+58.5\\\\=643.50

Hence, John will resell the bike at $643.50

Elisa has 6/14 pounds of flour. She would like to divide the flour equally into 5 bags. How much flour will be in each bag?
spayn [35]

(6/14)/5

5 in fraction form is 5/1.

To divide fractions, you flip the second fraction and multiply.  This problem becomes:

6/14 * 1/5


6*1=6

5*14=70

6/70=3/35


There will be 3/35 pounds of flour in each bag.


Hope this helps!!

1.94x - 10/8x + 4.32 = [2(1.15x+8.5)]
kipiarov [429]
1,94x-\frac{10}{8}x+4,32=[2(1,15x+8,5)]\\\\
1,94x-1,25x+4,32=2,3x+17\\\\
0,69x+4,32=2,3x+17\ \ \ |Subtract\ 2,3x\\\\
-1,61x+4,32=17\ \ \ |Subtract\ 4,32\\\\
-1,61x=12,68\ \ \ |Divide\ by\ -1,61\\\\\boxed{x\approx7,9}

You have 3 gallons of brown stock. You need 6 cups to make one serving of braised short ribs. How many servings can you make?
Vilka [71]

Answer: 8 servings can be made

Step-by-step explanation:

Concept:

As we can see from the question there are two different units applied [gallons] and [cups]; therefore, we need to do the unit conversion.

<u>1 gallon = 16 cups</u>

Solve:

Given there are 3 gallons of brown stock, we need to convert gallons into cups.

  • 1 gallon = 16 cups
  • 3 gallons = 16 × 3 = 48 cups

Then, divide 48 cups by 6 cups to find out how many servings can be made.

  • 48 cups / 6 cups = 8 servings

Hope this helps!! :)

Then all you do is add the numerators together so the answer is 33/8.
