Thank you for the opportunity to help you with your question!

Value of 1 dime=$0.10

Value of 1 nickel=$0.05

Let Sue have x dime and y nickel.

Then,

Total value=0.1x+0.05y=1.90  …(1)

Also, x-y=10   ….(2)

From (2) we have x=10+y

Putting value in 1, we have

x=16

y=6

So, sue has 16 dimes and 6 nickel.


Please let me know if you need any clarification. I'm always happy to answer your questions.
