Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(subtract like terms) (aka. 20c - 12c, 15r - 22r, 75p - 65p, 50e - 70e)
8c - 7r + 10p - 20e
A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21
63 nickels
B) d +2 = q
d + 2 = 21
19 dimes
