The formula should calculate the total amount that the customer should pay, after discount (if any) has been applied. Answer =IF(A1<500,A1*B1,IF(A1<2000,A1*B1*.95,A1*B1*.90)) =IF(A1<500, A1*B1, IF(A1<2000, A1*B1*.95, A1*B1*.90)) =A1*IF(A1<500,B1,IF(A1<2000,B1*0.95,B1*0.90))

152 Practice Question Question (Excel) What critical error is inherent within the following formula, assuming that it is entered into cell BB5 of the same worksheet? =IF(AVERAGEIF(AA2:AA6, ">55000") <> (SUM(BB2:BB6)), "D9") Answer There is no argument for the value_if_false portion of the IF statement D9 is a valid cell reference and should not be included in a text string There are too many sets of parenthesis within the IF function Cell references in the formula refer to the formula's result, thus creating a circular reference The ampersand sign ("&") is missing from the AVERAGEIF function

153 Practice Question Question (Excel) Assume that your insurance company offers three different payment plans for paying the premium on your vehicle. If you pay the six-month premium of $500 by the due date, you will owe only that amount. If you elect a "Monthly" payment option, the insurance company will bill you five times over the six-month period for 20% of the amount due plus a service fee of $5 per billing cycle for not paying the entire amount due initially. If you choose a "Quarterly" option for payment, you will be billed twice for half the premium due plus a service fee of $3 per billing cycle for not paying the entire amount in full. Create a formula in the answer space provided that will determine the correct amount to charge the customer for the initial bill payment based on a "Monthly" or "Quarterly" selection vs. all at once. Note: You should use these two given payment terms as defined names for the payment type selected in your formula. Answer =IF(Monthly,500*.2+5,IF(Quarterly,500/2+3,500)) =IF(Monthly, 500*.2+5, IF(Quarterly, 500/2+3, 500)) =IF(Quarterly,500/2+3,IF(Monthly,500*.2+5,500))

154 Practice Question Question (Excel) Review the accompanying workheet image containing employee information and then provide an answer in the blank space below. Salespeople who have been employed for more than six years and have annual sales of more than $22,000 are to be assigned a job level code of 2. All other employees should be assigned a job level code of 1. Without using a nested IF statement, create a formula in cell E2 that will assign an appropriate job level for Linda. The formula must then be copied down the entire column so that it will work for all of the other employees. Answer=IF(AND(C2>22000,D2>6),2,1)

155 Practice Question Question (Excel) Carefully examine the accompanying worksheet image. Airline passengers may have to pay a separate fee for checked bags at the time they obtain a boarding pass for their initial flight. If cell A1 contains the number of checked bags, provide a formula using only the cell references in the accompanying table that will correctly determine any baggage handling fee(s) that passengers must pay for their luggage. Note: The fee for the second bag is in addition to that charged for the first piece of checked luggage. Answer =IF(A1=B4,C4,IF(A1=B5,C4+C5,C3))

156 Practice Question Question (Excel) A local gas station is offering a discount on fuel to any customer that uses their debit card to make a significant purchase of fuel. Assume the following business rules apply to the sale: The number of gallons pumped is stored in cell A1 of a worksheet The baseline price per gallon (PPG) is provided in cell B1 of the same worksheet A named field (Debit) has been set-up in the point of sale (POS) hardware to indicate the use of a debit card with a Boolean TRUE condition For customers who use their debit card and purchase at least ten gallons of fuel, the discount will be five cents per gallon No discount for fuel will be given to customers who pay in cash or with a credit card Create a formula that will determine the total amount that a customer will pay for their fuel purchase whether they use cash, credit or a debit card. Answer =IF(AND(A1>=10,Debit),A1*(B1-.05),A1*B1) =IF(AND(A1>=10, Debit), A1 * (B1 -.05), A1*B1) =A1*IF(AND(A1>=10,Debit),B1-.05,B1) =A1 * IF(AND(A1>=10, Debit), B1-.05, B1)
