Problem Analysis

We are given that there were 12 more electric kettles than coffee makers in a store. We need to determine how many more electric kettles there are if only 5 coffee makers were sold.

Solution

Let's assume the number of coffee makers in the store is C and the number of electric kettles is K. We are given that K = C + 12.

If only 5 coffee makers were sold, the new number of coffee makers in the store would be C - 5. Since the number of electric kettles remains the same, the new number of electric kettles would be K = (C - 5) + 12.

To find the difference between the new number of electric kettles and the original number of electric kettles, we can subtract the original number of electric kettles from the new number:

Difference = (C - 5) + 12 - K

Let's substitute the value of K from the given information:

Difference = (C - 5) + 12 - (C + 12)

Simplifying the equation:

Difference = C - 5 + 12 - C - 12

The terms C and -C cancel each other out, and the terms -5 and -12 can be combined:

Difference = -5 + 12

Simplifying further:

Difference = 7

Therefore, the number of electric kettles increased by 7 when only 5 coffee makers were sold.

Answer

The number of electric kettles increased by 7 when only 5 coffee makers were sold.

Explanation

Let's break down the problem step by step:

1. We are given that there were 12 more electric kettles than coffee makers in the store. 2. If only 5 coffee makers were sold, the new number of coffee makers in the store would be C - 5. 3. Since the number of electric kettles remains the same, the new number of electric kettles would be K = (C - 5) + 12. 4. To find the difference between the new number of electric kettles and the original number of electric kettles, we subtract the original number of electric kettles from the new number. 5. Simplifying the equation, we find that the difference is 7.

Therefore, the number of electric kettles increased by 7 when only 5 coffee makers were sold.
