Answer:
The first one!
Step-by-step explanation:
First make both denominators the same. Then compare
.05n + .10d = 6.10
n + d = 67
n = 67-d
.05(67-d) + .10d = 6.10
3.35 -.05d + .10d = 6.10
3.35 + .05d = 6.10
3.35-3.35 +.05d = 6.10-3.35
0.05d = 2.75
0.05d/0.05 = 2.75/0.05
d = 55
n + d = 67
n + 55 = 67
n = 12
There are 12 nickels
Check
0.5(12) + .10(55) = $6.10
.60 + 5.50 =$6.10
$6.10 = $6.10
