Question

A jar contains pennies, nickels and dimes. the number of dimes is 1 more than the nickels and the number of pennies is 6 more than the nickels. How many of each can be found in the jar if the total value is $4.80 ?

Answer 1

$4.80 is the same as 480 cents..
p(1)+n(5)+d(10)=480
dimes=nickels+1 -> d=n+1
pennies=nickels+6 -> p=n+6
(n+6)(1)+n(5)+(n+1)(10)=480
16n=464 -> n=29
d=(29)+1=30
p=(29)+6=35
