Discount is $2.70
After-discount price is $15.30
Step-by-step explanation:
To get the after-discount price, multiply $18 by (1.00 - 0.15), or, in other words, multiply $18 by 0.85. The after-discount price is $15.30.
Two ways to find the discount: one is to multiply $18 by 0.15; the other way is to subtract $15.30 from $18.
Answer:
Step-by-step explanation:
We assume your equations are intended to be ...

Then the profit equation is ...

The partial derivatives of profit with respect to x and y are zero when profit is maximized.
∂P/∂x = 0 = -2x +2y +2
∂P/∂y = 0 = 2x -18y +94
Simplifying, these equations are ...
Substituting the first into the second gives ...
x -9(x -1) = -47
-8x = -56
x = 7
y = 7 -1 = 6
The company will maximize profit by selling 7000 panels of type A and 6000 panels of type B.
