Final answer:
The cost of one skirt is $59.50 dollars.
Step-by-step explanation:
To find the cost of one skirt, let's assume the cost of the skirt is 'x' dollars. According to the given information, the dress cost $71.50 more than the skirt. Therefore, the cost of the dress is 'x + $71.50' dollars. Now, we can set up an equation to represent the total cost of the dress and 2 skirts:
Cost of dress + Cost of 2 skirts = Total cost
'x + $71.50' + 'x' + 'x' = $250.00
Combining like terms gives: '3x + $71.50' = $250.00
Subtracting $71.50 from both sides of the equation gives: '3x = $178.50'
Dividing both sides of the equation by 3 gives: 'x = $59.50'
Therefore, the cost of one skirt is $59.50 dollars.
