The city of Philadelphia has decided to mint a new coin called the “jawn,” and presents the value of the jawn in the form of a riddle: “Three jawns and 27 cents is worth the same as five jawns and 21 cents.” Which equation and solution correctly represents the value of one jawn? A 3j + 5j = 27 + 21; j = 6
B 3 + 27j = 5 + 15j ; j = 1/6
C 3j + 27 = 5j + 21; j = 6
D 3j + 27 = 5j + 21; j = 3
