Question

Amanda sells homemade birthday cakes for a profit of $39 per cake. She is considering switching to a new type of icing that will increase her profit, as expressed by the function y = 45x, where x is the number sold and y is the amount of profit.

How many more dollars will Amanda earn on each cake if she switches to the new material?

Answer 1

Amanda currently earns $39 per cake profit.

With the new icing,

y = 45x where x is the number sold and y is the amount of profit.

Amanda would earn $45 profit per cake because:

y = 45x when x = 1 cake gives y = 45*1 = $45 profit for the new icing cake.

How many more dollars will Amanda earn on each cake if she switches to the new material?

That would be: $45 - $39 = $6 per cake more profit with the new icing.
