To find out how many of the 280 watches sold would be women’s watches, we can use the ratio of women’s watches sold to total watches sold.
Adam sold 25 women’s watches out of 56 total watches. We can express this as a proportion:
\[ \text{Proportion of women's watches} = \frac{25}{56} \]
Now, to find out how many women's watches would be sold if he sold 280 watches, we can set up the equation:
\[ \text{Number of women's watches} = \left(\frac{25}{56}\right) \times 280 \]
Calculating this:
\[ \text{Number of women's watches} = \frac{25 \times 280}{56} \]
First, calculate \( \frac{280}{56} \):
\[ \frac{280}{56} = 5 \]
Now multiply by 25:
\[ 25 \times 5 = 125 \]
Therefore, if Adam sells 280 watches, we can predict that 125 of them would be women’s watches.
The correct answer is 125.
