Because larger jobs have certain economies of scale in setup and cleanup, a discount is given based on these estimated values to jobs based on their total size. Just below the grand total, determine the total discounted price of the job based on the following: a. If the total cost of the painting job is less than $1000, then there is no discount. b. If the total cost of the painting job is at least $1000 but less than $2500, then a 10% discount will be given (discount is calculated based on the grand total cost for all items and all rooms). c. If the total cost of the painting job is at least $2500 but less than $5000, then a 12% discount will be given. d. If the total cost of the painting job is $5000 or more, than a 15% discount will be given. (Again, do not enter these amounts directly in the formula. Reference them in the inputs worksheet. Use a LOOKUP function rather than an IF statement in your formula.)
