no this relation is not a function, because for each input (x), there is no output (y)
N=number of nickles
d=number of dimes
n is 2 times d
n=2d
total money is 1.20
convert to cens
120 cetns
5n+10d=120
n=2d
5(2d)+10d=120
10d+10d=120
20d=120
divide both sides by 120
d=6

X + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 195
(Make sure you don't add "x+5" because "x + 0" is an included term.)
5x + 10 = 195
5x = 185
x = 37
