Answer:
25 Nickles
Step-by-step explanation:
n + q = 38
0.05n + 0.25q = 4.50
n + q = 38
q = 38 - n
0.05n + 0.25q = 4.50
0.05n + 0.25(38 - n) = 4.50
0.05n + 9.5 - 0.25n = 4.50
-0.2n + 9.5 = 4.50
-0.2n = 4.50 - 9.50
-0.2n = -5
-0.2n/0.2 = -5/0.2
-n = -25
-n/-1 = -25
n = 25
well there is 7x4, 14x2, and 28x1 of course.
