Answer:
4000%
Explanation:
To calculate the percent markup, we need to first find the difference between the cost and the selling price: $2.00 - $0.05 = $1.95
Then, we can divide that difference by the cost and multiply by 100% to express the result as a percentage:
($1.95 / $0.05) * 100% = 3900%
So the percent markup on the liter of bottled water is around 3900%. Rounded to the nearest percent, this would be 4000%.
