Let's pretend that our current system of money was strictly Base Ten, so that the only currency that we used were pennies, dimes, one dollar bills, ten dollar bills, hundred dollar bills, thousand dollar bills and so on. Instead of drawing pictures of the money, these abbreviations for each kind of coin or bill will be used: penny (A), dime (B), one dollar bill (C), ten dollar bill (D), hundred dollar bill (E), thousand dollar bill (F), and so on. Form each sum by combining the two addends into one lump. Make exchanges as necessary so that the sum is represented by the least number of coins or bills. Write your answer for each in alphabetical order with no spaces or commas. a. ABBBCDDD + AAABBBBBBBCCC: b. ACCCCCCCCCEEE + AAAABBCCCCCCCC = c. AAAAAEEEEEEAAAAAEEEEEEE
