The if family of statements is used most effectively when the input is a scalar. Create a function to determine test grades based on the score and assuming a single input into the function. The grades should be based on the following criteria: Grade Score A B 90 to 100 80 to 90 70 to 80 60 to 70 с D E <60 Run your code for the following scores: 90, 75, 60 and 0.
6. Deriving the short-run supply curve Consider the competitive market for halogen lamps.
