Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Kurt, an artist, plans to paint and sell some miniature paintings. He just bought some brushes for $18, and paint and canvas for each painting costs $79; he will sell each painting for $85. Once Kurt sells a certain number of his paintings, he will be breaking even. How many paintings will that be? How much will Kurt have earned?Once Kurt has sold _____ paintings, his expenses and receipts will both equal $_____.
Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Kurt, an artist, plans to paint and sell some miniature paintings. He just bought some brushes for $18, and paint and canvas for each painting costs $79; he will sell each painting for $85. Once Kurt sells a certain number of his paintings, he will be breaking even. How many paintings will that be? How much will Kurt have earned?Once Kurt has sold _____ paintings, his expenses and receipts will both equal $_____.
Define Variables: Define the variables and write the equations.Let x be the number of paintings Kurt sells.Kurt's expenses for x paintings include the initial cost of brushes and the cost of paint and canvas for each painting.Total expenses = Cost of brushes + (Cost of paint and canvas per painting × Number of paintings)Total expenses =18+79x
Calculate Expenses: Kurt's earnings from selling x paintings will be the selling price per painting times the number of paintings sold.Total earnings = Selling price per painting × Number of paintingsTotal earnings = 85x
Calculate Earnings: To break even, Kurt's total expenses must equal his total earnings.Set the total expenses equal to the total earnings and solve for x.18+79x=85x
Set Equation: Subtract 79x from both sides of the equation to isolate the variable on one side.18+79x−79x=85x−79x18=6x
Isolate Variable: Divide both sides of the equation by 6 to solve for x. 618=66x3=x
Solve for x: Calculate the total earnings when Kurt has sold 3 paintings.Total earnings = 85xTotal earnings = 85×3Total earnings = $255
