About the same amount now depending where you buy it.
If a dollar bill were printed in 1977, it would be worth $1.00 right now (in 2008). If a $20 bill were printed in 1977, it would be worth $20.00 right now (in 2008). A candy bar that may have cost $0.05 in 1977 would cost around $0.75 now. But then, a candy bar isn't a dollar.
That depends on what sort of candy bar it is, where you live, when you buy the candy and in which specific store you shop.
A nickel.
25c
I don't know for sure, but I think the average cost for a candy bar was around 5 cents.
$1.00 Because if they are 50 cents each, then: 0.50 + 0.50 = $1.00
if you're buying 2 candy bars, then 1.00.
50 cents
10 cents
about 80 cents to $1
About 2 shillings.
5 cents
