Based on dimensional analysis and unit conversion theory we conclude that an area of 359 square inches is equivalent to an area of 2.5 square feet.
<h3>How to apply dimensional analysis in unit conversion</h3>
In this question we need to convert a magnitude in a given unit to an <em>equivalent</em> magnitude with another unit. According to dimensional analysis, <em>unit</em> conversions are represented by the following expression:
y = A · x (1)
Where:
- x - Original magnitude, in square inches.
- y - Resulting magnitude, in square feet.
- A - Conversion factor, in square feet per square inch.
Dimensionally speaking, area is equal to the product of length and length:
[Area] = [Length] × [Length]
And a feet is equivalent to 12 inches. Now we proceed to convert the magnitude to square feet:
x = 359 in² × (1 ft/12 in) × (1 ft/12 in)
x = 359 in² × (1 ft²/144 in²)
x = 2.5 ft²
Based on dimensional analysis and unit conversion theory we conclude that an area of 359 square inches is equivalent to an area of 2.5 square feet.

Answer:
The owners' cost of the candy bar is $1
Step-by-step explanation:
Assume that the owners' cost of the candy bar is 100%
∵ The owners' cost of the candy bar is 100%
∵ The candy store uses a 50% markup on cost
∵ The selling cost = owners' cost + markup
∴ The selling cost = 100% + 50% = 150%
∵ The candy bar sells for $1.50
→ That means 1.50 is 150% of the owners' cost
∴ 1.50 = 150% × owners' cost
→ Change 150% to decimal by divide it by 100
∵ 150% = 150 ÷ 100 = 1.50
∴ 1.50 = 1.50 × owners' cost
→ Divide both sides by 1.50
∴ 1 = owners' cost
∴ The owners' costs = $1
∴ The owners' cost of the candy bar is $1
