I have a box of nickles and dimes. When I count the money,
I notice that I have exactly $10, and that there are 144
coins in the box. How many dimes and nickles are in the box?

>>... there are 144 coins in the box....<<


Translation:

(NUMBER OF NICKELS) 

plus 

(NUMBER OF DIMES)

equals

144

or   N + D = 144

>>... When I count the money, i notice that i have exactly $10...<<


Translation:

(5 cents times the NUMBER OF NICKELS) 

plus 

(10 cents times the NUMBER OF DIMES) 

equals

1000 cents  ($10 is 1000 cents 

or  5N + 10D = 1000

Solve this system by substitution or elimination  



Answer: 88 NICKELS and 56 DIMES.
