Sagot :
Answer:
17 nickels, 32 quarters
Step-by-step explanation:
n + q = 49
.05n + .25q = 8.85
Multiply the 2nd equation x 4 to make the q's the same amount
4(.05n + .25q = 8.85)
0.2n + q = 35.4
Now subtract the first equation
n + q = 49
- .2n + q = 35.4
.8n = 13.6
n = 17 There are 17 nickels
n + q = 49, so 17 + q = 49
q = 32
