Question

1)

A cake recipe requires 4 eggs, 12 lb. flour, 14 lb. sugar, and two ready-
made edible flowers. How much will it cost to make two cakes? Use the
following data: eggs = $1.00/dz; flour = $2.50/lb; sugar = $4.50/Lb; and
flowers = 5 cents each.

Answer 1

$186.86

Explanation:

4 eggs cost:

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

`(1)/(12)=(x)/(4)\\12x=4\\x=0.33`

So, 4 eggs cost $0.33 approx

12 lb. flour cost:

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

2.5 * 12 = $30

14 lb of sugar cost:

4.50 dollar per pound means 14 pounds would cost:

4.5 * 14 = $63

2 ready-made edible flowers cost:

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
