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

Lines s and t are perpendicular if the slope of line s is 5 what is the slope of line t
ycow [4]

The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
