A baker sells 80% of his biscuits and is left with 80 biscuits. How many biscuits did he begin with?Choose 1 answer:600660560400

1. Break Down the Problem

Let $x$ be the total number of biscuits the baker started with. According to the problem, the baker sells 80% of his biscuits, which leaves him with 20% of them. We know that 20% of the total equals 80 biscuits.

2. Relevant Concepts

To find how many biscuits he started with, we need to set up the equation based on the relationship: $0.2x = 80$

3. Analysis and Detail

Now, we can solve for $x$: $x = \frac{80}{0.2}$ Calculating the right side: $x = 80 \div 0.2 = 80 \times 5 = 400$

4. Verify and Summarize

To verify, we can check whether 80% of 400 equals 320, and thus the remaining biscuits should be: $400 - 320 = 80$ The calculation holds true.

Final Answer

The baker began with 400 biscuits.
