Jill has $9.96 in nickels, pennies, and dollar bills in her bank. If she has 12 more pennies than nickels and 5 less dollar bills than nickels, how many of each does she have.
Number of pennies:P Number of nickels:N Number of dollar bills:D P=N+12 N=D+5 1P+5N+100D=996 ^given Therefore P=(D+5)+12 P=D+17 Plug back into main equation (D+17)+5(D+5)+100D=996 Combine like terms 106D+42=996 106D=954 D=954/106=9
