Question

You have a total of 200 Coins, Consisting of nickels and dimes. The total value of the 200 Coins is $16.85. How many of each do you have?

Answer 1

Below

Explanation:

n = # nickels value = 5n

(200-n) = # dimes value = 10(200-n)

summed, these equal 1685

5n + 10(200-n) = 1685

5n + 2000 -10 n = 1685

-5n = -315

n = 63 then dimes = 137
