Answer:
The quantity of the mark is $11.5.
Explanation:
- The cost of each umbrella = $23
The quantity of the mark can be determined by multiplying the cost of the umbrella by the markup percentage.
Thus,
The quantity of the mark = 23 × 50%
= 23 × 50/100
= 23 × 1/2
= 23 × 0.5
= $11.5
Therefore, the quantity of the mark is $11.5.
