Answer:

Amanda will earn $6 more using the new material

Explanation:

We are given that, using the old material, Amanda's profit from selling one cake was $39

Now, using the new materials:

We are given the equation:

y = 45x where y is the profit earned and x is the number of cakes

For selling one cake (x=1), Amanda's profit will be:

y = 45(1) = $45

To get the increase in profit, we will simply subtract the old profit from the new one

This means that:

Increase in profit = 45 - 39 = $6

Hope this helps :)
