Question 352060
A vending takes only nickels and dimes. There are 5 times as many dimes as nickels in the machine. The face value of the coins is $4.40. How many of each coin are in the machine?
...
let the number of nickels in the machine be x
number of dimes = 5times the nickels = 5x
..
the total value = $4.40 
In cents it will be 440
...
1 nickel is 5 cents: x nickels will be 5x cents
1 dime = 10 cents : 5x dimes = 50x cents
..
The sum of these two = 50x+5x = 55x
which is equal to 440 cents
55x= 440
x=440/55
x= 8 the number of nickels.
dimes is 5 times the nickels . so dimes = 5*8 = 40 dimes.

5*8 + 40*10 = 440 cents which is in the machine
