Answer:

$186.86

Step-by-step explanation:

<u>4 eggs cost:</u>

1 dollar per dozen (12 eggs), so by unitary method (ratios), we can find cost of 4 eggs. Shown below:

\frac{1}{12}=\frac{x}{4}\\12x=4\\x=0.33

So, 4 eggs cost $0.33 approx

<u>12 lb. flour cost:</u>

2.50 dollar per pound, so 12 pounds would simply cost:

2.5 * 12 = $30

<u>14 lb of sugar cost:</u>

4.50 dollar per pound means 14 pounds would cost:

4.5 * 14 = $63

<u>2 ready-made edible flowers cost:</u>

5 cents for each flower means 2 flowers would cost:

5 cent = 0.05 dollars

0.05 * 2 = $0.10

We add all up to find cost of 1 cake. Shown below:

Cost of 1 cake = $0.33 + $30 + $63 + $0.10 = $93.43

Cost of 2 cakes = $93.43 * 2 = $186.86

fgiga [73]

Answer:

5.66 years

Step-by-step explanation:

450 x 1.025^(n) = 450 + 67.50

450 x 1.025^(n) = 517.50

1.025^(n) =(517.50 / 450)

1.025^(n) = 1.15

n = ln(1.15) / ln(1.025)

n = 5.66

(2x/3)-(5x/9)-(x/6)-(5x/12)=13/2 this equation is equivalent to:
agasfer [191]

Answer:

-17x=234

Step-by-step explanation:

Given that:

\dfrac{2x}{3}-\dfrac{5x}{9}-\dfrac{x}{6}-\dfrac{5x}{12}=\dfrac{13}{2}

\dfrac{72x-60x -18x-45x }{108} = \dfrac{13}{2}

\dfrac{-51x }{108} = \dfrac{13}{2}

-102x =    1404

-\dfrac{102x}{6} = \dfrac{1404}{6}

-17x = 234

Option B

  • First week: $200
  • Second week: $220
