The worksheet tab named "Problem 3 and 4" from Supplement_Spreadsheet has the prime numbers from 2 up to 23 entered in order in cells A7, B7, C7, A8, B8 and C8. Cell C12 contains the formula *=A7*B7*A8*c8", and displays the value 546 (which is equal to 2*3*7*13). YOUR TASK: Modify the formula in A12 by doing nothing but adding dollar signs ($). Do not change the order of the cell in the formula. Create a formula in A12 that does not change the value that appears on cell A12, and that you can copy and paste to the cell B13 so that this cell shows the value 6279. Hint 6729 = 3*7*13*23, or B7A8*08*09 QUESTION 3: Which of the following formulas uses an absolute row reference and a relative column reference? a) A10 b) A$10 c) $A10 d) $A$10 e) None of the above QUESTION 4: What formula did you enter in cell C12? (Enter your answer with no spaces, with capital letters, and with the = equal sign, for instance, if your formula in C12 was =$A$7*$B$7*$A$8*$C$8 then enter exactly =$A$7*$B$7*$A$8*$C$8 in the answer box. Double check your answer, because typos will make it wrong
