Markup = $4
b) markup as a percentage of cost is 33.3%
Step-by-step explanation:
Markup
markup = selling price - cost
= $13 - 9
... markup = $3
Markup as a Percentage of Cost
To find the percent markup, divide the markup by the reference value and multiply the ratio by 100%. The reference value for markup is usually cost price, but sometimes may be selling price.
... markup / cost × 100% = 3/9×100% = 33 1/3% ≈ 33.3%
The difference between the given values as a whole number is 27
<h3>Finding the difference between values</h3>
To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value.
Given the following expression
44 - 17
This can also be expressed as
44 = 40 + 4
17 = 10 + 7
Substitute
44 - 17 = (40 + 4) - (10+ 7)
Expand
44 - 17 = 40 + 4 -10 - 7
44 - 17 = 40 - 10 + 4 - 7
44 - 17 = 30 - 3
44 - 17 = 27
Hence the difference between the given values as a whole number is 27
