How many nickels were there?

Question

from his paper route, brody collected $5.55 in nickels and dimes. The number of nickels was 6 more than the number of dimes.

Answer 1

N = D+6

 

 

5n + 10D = 555

 

n + 2d = 111

 

d+6 + 2d = 111

 

3d = 105

 

d = 35

n = 41

 

 

CHECK:

35 x 10 + 41 x 5 

= 350 + 205

= 555
