Determine which table has the correct values for A, B, and C.

Donuts 3 4 5 7
Cost 13.80 27.60 34.95 55.20

Donuts 2 4 5 8
Cost 13.80 27.60 34.95 55.20

Donuts 3 4 5 6
Cost 13.80 27.60 34.50 55.20

Donuts 2 4 5 8
Cost 13.80 27.60 34.50 55.20

Answer 1

Explanation:

The table with correct values of A, B and C is,

⇒ Donuts 2 4 5 8

Cost 13.80 27.60 34.50 55.20

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The table below shows the ratios of boxed donuts to the cost.

Donuts A 4 5 C

Cost 13.80 27.60 B 55.20

Now, By definition of ratio, we get;

⇒ A / 13.80 = 4 / 27.60

⇒ A = 13.80 × 4 / 27.60

⇒ A = 2.00

And,

⇒ 4 / 27.60 = 5 / B

⇒ B = 5 × 27.60 / 4

⇒ B = 34.5

⇒ 4 / 27.60 = C / 55.20

⇒ C = 55.20 × 4 / 27.60

⇒ C = 8

Thus, The table with correct values of A, B and C is,

⇒ Donuts 2 4 5 8

Cost 13.80 27.60 34.50 55.20
