Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.
<h3>How to derive a unit conversion formula?</h3>
Kingsley knows the conversion rate between inches and centimeters and wants to derive a formula. Both the inch and the centimeter are length units and we can represent it by the following ratio:
y / x = 2.54 (1)
Where:
- y - Length, in centimeters.
- x - Length, in inches
Then, we clear the variable x in (1) to find the unit conversion formula:
x = y / 2.54 (2)
Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.

Answer:
$1.59 for a pint,
two dollars for a quart,
299 for a gallon
Step-by-step explanation:
Since, rate is used to compare different kinds of quantities and it is the ratio of the quantities,
Also, unit rate states the amount of first quantity corresponding to the unit amount of second quantity,
When we talk about the unit rates for a quantity,
Then it shows the price of the quantity per unit amount.
Thus, by the above explanation it is clear that,
The unit price for representing the price of juice would be,
$1.59 for a pint,
two dollars for a quart,
299 for a gallon.
Note : we do not consider 'one dollar for 12 ounces' a unit price because it is not the price per 1 ounce.
The answer should be (-4,2)
