The easiest way is to convert everything to cents first. - Seven nickels = 35 cents - Two quarters = 50 cents - so 7 nickels to 2 quarters is the same as 35/50, or 0.7 as a decimal number.
4 quarters = 1 dollar = 100 cents
$3 would be 12 quarters, 35 cents would contain one quarter and one dime. So your answer would be 13 quarters and 1 dime.
The algebraic formula for this problem has the form 25x + 10(35-x) = 515 where x is the number of quarters (times 25 cents) and (35-x) is the number of dimes (times 10 cents) With the result that 25x + 350 - 10x = 515, yielding 15x = 165, and x = 11 So James has 11 quarters and 24 dimes, (2.75 and 2.40) equalling $ 5.15 total.
3 Quarters... Otherwise, 75 cents.
35 quarter
14 Quarters = $3.50 28 nickels = $1.40 To get this answer you simple add 2 nickles to one quarter which = 35 cents divide 4.90 by 35 which equals 14 14 will be the number of quarters and double that, 28 will be the number of nickels

5 * 25 = 125 cents 125 cents/25 cents = 5 quarters =========
Oh, dude, you got me doing math now? Alright, let's see... so a dime is worth 10 cents and a quarter is 25 cents, so if you divide 25 by 10, you get 2.5. Therefore, 14 quarters would be equivalent to 35 dimes. Math can be fun, right?
