Answer:
10 ways
Step-by-step explanation:
When we do not use any quarters, we can use 0,1,2,3,4, or 5 dimes only
and the rest of the 50 cents, if any, in nickels. That's 6 ways.
If we use only 1 quarter, then we can use 0,1, or 2 dimes, and
the rest is nickels. That is 3 more ways.
if We can use 2 quarters. That's 1 more way.
So together there are 6+3+1 = 10 ways. in total
hope you got the point.
