#1 is correct
#2.
<<She has four more pennies than quarters> ----> q = p-4
<<one more nickel than pennies> ----> n = p+1
Now form the value equation :
25q + 5n + p = 308
25(p-4) + 5(p+1) + p = 308
take it from there
(your 14 nickels is correct, 13 pennies and 9 quarters)
Here are two more problems I have for homework tonight. I have gotten answers, but I used "guess-and-check" and could not find an equation like I am supposed to. If you answer, please tell me if my answer is correct, walk me through your way of solving it, and if you can, show me an equation. Thanks!
#1: In a basketball game, the United States has four times as many points as Croatia. A Croatian makes a basket for three points, at which point the United States only has three times as many points. How many points does the United States have?
Here is the equation that I have:
3c + 9 = 4c
Which is a simplifyed version of:
3(c+3) = 4c.
Are my equations correct? The answer I got was 36 points.
#2: Sue has $3.08 in pennies, nickels, and quarters. She has four more pennies than quarters and one more nickel than pennies. How many nickels does she have?
I do not know the equation for this one. My answer was 14 nickels.
Again, thank you so much for any help you can give me!

Thank you so much for your help! :)
meh.
keep it clean here.
Could you please explain why the equation for the first answer is 3(c+3) and not 4c - 3??
oh wait your first answer is incorrect, sorry for a 15yrs delay, i was 1yrs old when u asked that question...
anyways, lets say croatia has 21points, and the US has 84points which is 4C, when croatia scores a basket worth 3 points they now have 24points but the US has 4C - 3, not plus (but minus) so that our answer stays 84 points for the US team and not 87.
now back to the question,
1....... U = 4C
2........U = 4C - 3 = 3C (when crotia scores that basket the US will only have 3 times as much points)
C = 3, U = 4(3)-4 = 12-3 = 9, the answer for US points in the game after Croatia scored the basked is 9 points, and before they scored the basket (which i think is not required by the question), US points is 12.
Thanks
