Xavier sells homemade necklaces for a profit of $22 per necklace. he is considering switching to a new type of pendant that will increase his profit, as expressed by the function y = 29x, where x is the number sold and y is the amount of profit. how many more dollars will xavier earn on each necklace if he switches to the new material? explain how you found your answer.

Well if x is the amount sold and y is the profit, then the original equation would be y = 22x since originally he was selling them for $22 dollars each. That means that in the equation y = 29x, 29 is the amount of profit per each necklace. From here it's just simple subtraction. New profit - Old profit = How much more earned $29 - $22 = $7 extra earned per necklace. he would save $7.
