you have a Jar full of nickels and dimes there are a total of 117 coins the value of the coins is $8.55 how many of each do you
ycow [4]

n= each nickle = 0.05 dollars

d= each dime = 0.1 dollars

so

0.05n + 0.1d = 8.55

and

n + d = 117

d = 117 - n

solving the 2 equations for the 2 variables:

0.05n + 0.1(117 - n) = 8.55

- 0.05n = 8.55 - 11.7 =  - 3.15

n =  \frac{ - 3.15}{ - 0.05}  = 63 \: nickles

n + d = 117

d = 117 - 63 = 54 \: dimes
