Create a column called “Credit”. If the “Score” of the customer is “less than” 40, then give a “Poor” value in the Credit column. If the “Score” of the customer is “equal to” or “higher than” 40 but “equal to” or  “less than” 70, then give an “OK” value. If the “Score” of the customer is “higher than” 70 but “less than” 90, then give a “Good” value. If the “Score” of the customer is “equal to” or “higher than” 90, then give an “Excellent” value. You must use a lookup function WITH an ARRAY Form for this column. Be sure that you implement the EXACT cutoff here using a range of scores with no more than 4 rows. No points will be given for using IF function.

On behalf of the company, draft a formal letter to the customers who are rated “Poor” (be creative). Use another worksheet for this.
