Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?
a. 0.1n + 0.05(n – 175) = 13.30
b. 0.1n + 0.05(175 – n) = 13.30
c. 0.1(n – 175) + 0.05 = 13.30
d. 0.1(175 – n) + 0.05n = 13.30

Best ResponseYou've already chosen the best response.1175 is the total number of coins you're using n represents how many of them are nickles; if you are only using nickles and dimes, what does 175  n equal?

Best ResponseYou've already chosen the best response.1or to make it easier: if 175 = total number of nickels and dimes used; (175 total coins)  (n amount of nickles) = ?

Best ResponseYou've already chosen the best response.1a dime equals $.01 and a nickel equals $.05 so what you want to find is the nickels, so the n would go with the nickels as .05n, but also 175

Best ResponseYou've already chosen the best response.1I don't know if that helps, but what do you think the answer would be

Best ResponseYou've already chosen the best response.1Because now you know that it the answer is neither a or b which do you think its going to be?

Best ResponseYou've already chosen the best response.1No, I meant its either c or d because .5 has to be multiplied by n

Best ResponseYou've already chosen the best response.1also you know that n is going to be smaller than 175 so you would have to subtract n from 175 like this: 175n Hope this helps!

Best ResponseYou've already chosen the best response.0kind of but still confused. thanks though

Best ResponseYou've already chosen the best response.1No its d because you have to subtract n from 175 like this: 175  n, as 175 is total amount of coins and your answer would become negative

Best ResponseYou've already chosen the best response.0The answers from Mathematica 9 are attached. Perhaps you can use those and work backwards.
