The cost per ounce of a drink, c, varies inversely as the number of ounces, n. Six ounces of the drink costs 60 cents per ounce.
kaheart [24]

Answer:

c = 360/n

Step-by-step explanation:

From the question, we are told that:

The cost per ounce of a drink, c, varies inversely as the number of ounces, n.

Mathematically this is expressed as:

c ∝ 1/n

Using the constant of proportionality k

c = k/n

Six ounces of the drink costs 60 cents per ounce.

c =60 cents per ounce

n = 6 ounces

Mathematically we have

c = k/n

60 = k/6

Cross multiply to find the constant k

k = 60 × 6

k = constant of proportionality = 360

Therefore, using the mathematically expression "c = k/n" the equation that represents this relationship is

c = 360/n

Rzqust [24]

Answer:

2.2084384 in cents, and 22.084384 in dollars

Step-by-step explanation:

Apologies in advance if I've got something wrong, it's currently 12:08 at night for me njnhrj

First we'd like to figure out how much we have after calculating the weight left over after charging for the first ounce.

7.90137-1=6.90137

Multiply by .32, and you've got your sum in cents; 2.2084384‬

Divide this by 0.1 and you've got it in dollars; 22.084384
