You pay $2.40 for 3/4 pound of grapes your friend buys a pound of grapes at the same time and estimates that he will pay $1.80 w
LenKa [72]

I would say your friends assumption is wrong. Why?


Because, if you payed $2.40 for 3/4 pounds of grapes, your friend should pay more for an entire pound, not less.

I need help working this out
Leona [35]

I think in this situation the best method would be a guess and check. You know that there are 8 dimes more than there are nickels. So just keep increasing each number by one until you reach $1.40. If there were 9 dimes and 1 nickels it would add up to $0.95. If there were 10 dimes and 2 nickels, it would add up to $1.10. If there were 11 dimes and 3 nickels, it would add up to $1.25. If there were 12 dimes and 4 nickels, it would add up to $1.40. So your answer is 12 dimes and 4 nickels.

I hope this helped!
