Answer:
520 g
Explanation:
Since we don't know the amount in the standard bag, we call its weight x.
The original bag contains 100% of its contents since 100% is the same as 1, or a full bag.
The limited edition bag has 25% more than the standard bag.
The limited edition bag has 100% of x + 25% of x.
100% of x + 25% of x = 125% of x = 1.25x
We are told the limited edition bag has 650 g of sweets.
Our equation is:
1.25x = 650
Divide both sides by 1.25
x = 650/1.25
x = 520
Answer: 520 g
