Jake had a piggy bank dipped with nickels quarters and dimes. He noted that he had three times as many dimes as quarters and four less than twice the number of dimes in nickels. Jake knee the total in the piggy bank was $20.20 what was his value in dimes ?
+36916 d = 3q
n = 2 * 3q -4
q
25 q + 10 * 3q + 5 (2*3q-4) = 2020
25q + 30 q + 30q -20 = 2020
85q = 2040
q = 24
then d = 3q = 72 dimes = $7.20
+36916 d = 3q
n = 2 * 3q -4
q
25 q + 10 * 3q + 5 (2*3q-4) = 2020
25q + 30 q + 30q -20 = 2020
85q = 2040
q = 24
then d = 3q = 72 dimes = $7.20
