You can put this solution on YOUR website! Guess and Check would be the best way to solve this problem.
Since a dime is worth 10 cents and a quarter is worth 25 cents, and there has to be 11 coins, We can just keep trying different things.
1st attempt: 6(.25)+5(.10) =
1.50+.50 = $2.00 (Not the answer)
2nd attempt: 5(.25)+6(.10) =
1.25+.60 = $1.85 (Not the answer)
3rd attempt: 4(.25)+7(.10) =
1.00+.70 = $1.70 (The answer)
After guessing and checking, We now know that the answer is 4 quarters and 7 dimes.
