In the stamp collection below. the denominations have not been entered. use the clues below to set up equations and determine the proper denominations. clue 1: the r stamps total 24 cents. r1 + r2 + r3 = 24 clue 2: the r stamps with animals total 16 cents. r1 + r2 = 16 combining this with clue 1, we know r3 = 8 clue 3: the stamps with animals total 20 cents. r1+ + s2 = 20 combining this with clue 2, we know s2 = 4 clue 4: the stamps with two animals total 13 cents. s2 + r2 = combining this with what we learned from clue 3, we know r2 = clue 5: the two stamps with a person total 22 cents. + t2 = 22 combing this with what we learned from clue 2, we know t2 = clue 6: the triangle stamps total 24 cents. t1 + = 24 combining this with what we learned from clue 5, we know = 10 clue 7: the stamps with mechanical devices total 20 cents. t1 + r3 + s1 = combining this with what we learned from clue 2 and clue 6, we know s1 = the s stamps total 11 cents. s1 + s2 + = 11 combining this with what we learned from clue 3 and clue 7, we know = 5
