About the same amount now depending where you buy it.
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.
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.
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
About 2 shillings.
Around 35 cents
10 cents
about 80 cents to $1
