Question

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

Answer 1

Hey there!

So the original profit is y=22x; x=number of necklaces and y=profit

New:
y=29x; x=number of necklaces and y=profit

Xavier will earn $7 more if he switches to his new plan because a keyword in the question is "How many more" and that usually means to subtract, so take away 22 from 29 and you get 7

Hope this helps!

Answer 2

Hello there! 

So, if he had a profit of $22 before, and now a profit of $29, based on the equation --
y = 29x

Then 29 - 22
=7

He will make 7 more dollars if he switches to the new material. 

Hope I helped!
