    It's not on sale.

    Shopper #1: I sure want that widgit. and look at the price. I have exactly enough to pay for it. All I have are coins though and I hate paying with coins. I'll comeback when I have bills.
    Shopper #2: I have a bill, do you have change for a dollar?
    Shopper #1: No
    What's the most the widgit could cost?

    american coins: (100 cents =1 dollar): half dollar(50 cents), quarter(25 cents), dime (10 cents), nickel (5 cents), penny (1 cent)

    .99 cents? what if shopper #1 just lied because she likes to save her coins, and she really did have change for a dollar!

    sometimes in the brain teasers section you should use your brain. Wrong answer number one
  5. Nov 15, 2005 #4
    I'm not an expert on US currency, but what are the highest value coins? If, say, there was a two-dollar coin, shopper #1 may have all the money in two-dollar coins and so no change for a dollar. Or even one-dollar coins, since a $1 coin would not be 'change' for a $1 bill. However, I see no upper limit to the cost of the widget in this case so I guess that's not it? Unless by shopper #2's offer of a dollar bill we can infer that shopper #2 knew the cost of the widget, in which case it's $1.

    but i did use my brain :) It was just the wrong answer... Well the widget could cost ... could it possibly be 1.69? 7 dimes... 70 cents... 3 quarters... 75 cents... 4 nickles... 20 cents... 4 pennies... and still no change for a dollar... unless there is a different mix of coins for a larger price.

    I wasn't being rude, but did you read your answer? go back and read it and tell me you really tried to come up with an answer

    yeah sorry, was just using some sarcasm... i should note that before i post, hard to tell over the net.

    we don't do sarcasm here. lol. I'm just screwing with you
  10. Nov 15, 2005 #9
    so is it 1.69? :)
  11. Nov 15, 2005 #10
    not even close
  12. Nov 15, 2005 #11
    I can't figure out a way to get above $1.19 (such as 50+25+4*10+4*1). The only "split" that would take me above a dollar is the 25 which keeps it from happening since there's no 25 in 4*10 and there isn't enough pennies to make another 5. I may be wrong, but that'd be my guess.
  13. Nov 15, 2005 #12
    If the answer is $1.19 (3 quarters, 4 dimes, and 4 cents), then the problem is poorly worded. The buyer is going to pay with coins whether they like it or not.

    Do you have half-dollar coins in the US? I've just come back from America and I don't remember seeing any - just loads of quarters!
  15. Nov 15, 2005 #14
    There are indeed half-dollar coins, though quater, dime, nickle and penny (25, 10, 5 and 1, respectively) are *way* the most common. The half-dollar is used pretty rarely, though they are definitly around. There have also been rounds of dollar coins for ages (gold/silver dollars, etc) though they've never caught on. I think they're planning another round of it. Most other systems I've seen seem to use coins up to $1-$2 in value and often remove the penny and possibly nickle value coins and round up/down at those ammounts. The public doesn't seem very willing to do either of these (I don't think they've even tried removing pennies, but dollar coins seem to be met with suspicion as well).

    Thanks for that LarrrSDonald, a similar thing occurs with our £2 coin. I've no idea how many are in circulation but there are many, many more £1 coins.

    Another way to make $1.19 cents is 1 quarter, 9 dimes and 4 cents is it not?
  17. Nov 15, 2005 #16
    how do you guys keep getting 1.19, i already posted a way to get to 1.69 without having an even dollar for change... but i think it's 1.74 uppon further examination. 9 dimes... 90 cents... 1 nickle... 5 cents.. 3 quarters.. 75 cents... 4 pennies... 4 cents... and in any of these variations, you cannot come to an even dollar. So i stand strong with my final answer of 1.74

    With those coins, you could easily make change for a dollar. For instance, 3 quarters, 1 nickel, and 2 dimes.
  19. Nov 15, 2005 #18
    Same with the previous "70 cents... 3 quarters... 75 cents... 4 nickles... 20 cents... 4 pennies...", the three quaters, two dimes and a nickle would work as would numerious other combinations.

    the reason we still have pennies is because it costs less than 1 cent to make one. pennies are free money for the treasury

    Yeah I have been thinking and all I can get is just $1.19. Oh well I guess I will have to try a little harder.
