Final answer:
The equation that can be used to find the number of pieces of art Ann must sell for her sales to equal her expenses is 89 + 394 + 14a = 35a.
Step-by-step explanation:
To find the number of pieces of art Ann must sell for her sales to equal her expenses, we can use the equation:
89 + 394 + 14a = 35a
Where 'a' represents the number of pieces of art. The left side of the equation represents Ann's expenses, which consist of the software cost, online advertisement cost, and the cost of printing and framing each piece of art. The right side of the equation represents Ann's sales, which is the selling price of each piece multiplied by the number of pieces sold. By solving this equation, we can find the value of 'a'.
