Answer:

12 dimes and 16 nickels

Step-by-step explanation:

D +N =  28

  N = (28-D )

I will multiple the next by 100 to avoid decimals dines: 10 instead of  0.10....

10D + 5(28-D) = 200

10D + 140-5D = 200

5D = 60

D = 12   (12 dimes)

28-12 = 16  (16 nickels)

12x 0.10 + 16 X 0.05 = 2.00

$1.20 + $0.80 = $2.00
