Answer 1

$1.94 was the original price of the candy bar before the increase.

Solution

Candy bars have increased in price by 8% in recent years.

If today's price is approximately $2.10

Let X be the original price.

$2.10 be the 108% of original price X

So we can write, X(108)/100 = $2.10

X =( 2.10 x 100)/108 = $1.94

$1.94 was the original price of the candy bar before the increase
