Respuesta :
1 nickel = 5 cents
1 quarter = 25 cents
Let the number of nickels be = n
Let the number of quarters be = q
As mentioned, Chris has 4 times as many nickels as quarters
so, n=4q ----- (1)
The coins have a combined value of 180 cents, so
[tex]5n+25q=180[/tex] ----- (2)
Putting n=4q in equation (2)
[tex]5(4q)+25q=180[/tex]
[tex]20q+25q=180[/tex]
[tex]45q=180[/tex]
[tex]q=4[/tex]
Hence, quarters are 4
As, n=4q
[tex]n=4\times4=16[/tex]
Hence, nickels are 16
