n = nickels value = 5n

d = dimes = (53-n) value = 10 ( 53-n) summed, the values = 400

5n + 10(53-n) = 400 solve for 'n'

*Ms. Jones has 53 coins. They are all nickels and dimes. The total value of the coins is $4.00. How many nickels does she have?*

Start by noting that IF all 53 coins are dimes, then her total would be 5**.**30.

For every nickel she substitutes for a dime, the total goes down 5¢

She needs to reduce the total 1**.**30. It takes **26 nickels** to make 1**.**30.

__Check answer__

So, if Ms Jones substitutes 26 nickels for 26 of the dimes,

she would end up with 27 dimes and 26 nickels.

27 dimes is 2**.**70

26 nickels is 1**.**30

total 4**.**00
