umm so 1 euro+50c+20c+5c=1.75 euro:)
50 = sx3
10+5c
Tentatively I will say $4.35, with for instance: 19 x 20c 1 x 50c 1 x 5c It's possible that a rigorous method exists, but this is just a fudged guess. Any advances on it?
two
If that is an equation: 5c = 10 then the value of c is 2

48 i think
One way for 16 Australian coins to equal 95 cents is as follows: * 13 5c coins and 3 10c coins 13 x 5 = 65 3 x 10 = 30 30 + 65 = 95 cents
There are 14 five cent coins in 70 cents.
15.386.000 coins were struck of this type. Value: about 10 dollars.
5c is equal to 5 times c, which means 5 times any number represented by c.
It is not possible to make 25 cents from 14 coins (US currency) There are only 1, 5, 10 and 25 cent coins Test: 14 x 1c = 14c, insufficient value 13 x 1c (=13) + 1 x 5c (=5) totals 18c, still not enough 12 x 1c (=12) + 2 x 5c (=10) totals 22c, still not enough. 11 x 1c (=11) + 3 x 5c (=15) totals 26c. Too much! If you use a 10c coin, you have to make the balance of 15c with 13 coins! Not possible! Of course, if you have 14 coins, which includes 10 x 1c (=10), and 3 x 5c (=15), you will easily make a total of exactly 25c, but only if you don't include the 14th coin!
The echidna is on the Australian 5c piece.
3 dimes 13 nickles 5 pennies
80, because there are 400 cents in 4 Dollars, and 400 divided by 5 = 80.
