12% increase

30% decrease

12% decrease

30% increase

Let’s break this down:

- The watch price drops by 20%. So, if the original price is $100, it becomes $80.

- The number of watches sold goes up by 40%. So, selling 100 watches turns into selling 140.

- Sales = price × quantity. Old sales: $100 × 100 = $10,000. New sales: $80 × 140 = $11,200.

- What’s the percent change? $\frac{11,200-10,000}{10,000} \times 100 = 12\%$ increase.

Looking at the options:

- Option 1, 12% increase – ?? this is it. The math checks out.

- Option 2, 30% decrease – way off, sales actually went up.

- Option 3, 12% decrease – nope, that would mean sales dropped.

- Option 4, 30% increase – close guess, but it’s too high.
