Emily went to the store and bought art supplies for $20 and 2 skirts that cost the same amount of money. She spent a total of $50. How much did Emily pay for each of the skirts?
Thoughts? Step-by-step reasoning:
First, you need to set up the problem with the information given. The cost of the skirts and art supplies must equal $50. Since we know that the cost of the skirts is the same price and that she bought art supplies for $20, we can set up an equation: 2x + 20 = 50, with x being the cost of the skirts. To solve the equation, subtract 20 from both sides, to give you the new equation: 2x = 30. Solve for x by dividing both sides of the equation by 2, 2x / 2 = 30 / 2 gives you x = 15. Therefore, each skirt cost $15.
Thus, the answer is 15.
