2.50 can be made up from 10 quarters or 25 dimes, for the first two ways. The smallest number of quarters that can be substituted for dimes without changing the sum is two, substituted for five dimes. Therefore, you can have: 20 dimes + 2 quarters, 15 dimes + 4 quarters, 10 dimes + 6 quarters, or 5 dimes + 8 quarters, four additional possibilities for a total of six..
The coins in the store's cash register total $12.50. The cash register contains only nickels, dimes, and quarters. There are twice as many dimes as nickels. There are also twice as many quarters as dimes. How many quarters are in the cash register?
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.
d = q + 3; 10d + 25q = 345. 10(q + 3) + 25q = 345 ie 35q = 315 so q = 9 and d = 12. Check: 9 quarters = $2.25, 12 dimes = $1.20, total $3.45.QED
$1.19 is the total.
