James has a change jar that contains only half dollars and nickels. He has 65 coins which add up to a total of $22.15. How many of each type of coin does he have?

Question

i also need an equation

Answer 1

Let x = number of half dollars and y = number of nickels

x + y = 65

0.5x + 0.05y = 22.15

-0.5x - 0.5y = -32.50

0.5x + 0.05y = 22.15

-0.45y = -10,35

y = 23 and x = 65 - 23 = 42

We need 42 half dollars and 23 nickels.

hd+n=65

hdv+nv=22.15

There's different answers; the easiest is 44hd+3n=22.15.
