First, we determine Jamal's rate of toy production. He averages 8 toys every 5 days, which means he produces:
\[ \text{Toys per day} = \frac{8 \text{ toys}}{5 \text{ days}} = 1.6 \text{ toys per day} \]
Next, we want to find out how many days it will take to fill an order of 75 toys. We can calculate this using the formula:
\[ \text{Days needed} = \frac{\text{Total toys needed}}{\text{Toys produced per day}} = \frac{75 \text{ toys}}{1.6 \text{ toys per day}} \]
Calculating that gives:
\[ \text{Days needed} = \frac{75}{1.6} \approx 46.875 \]
Rounding to the nearest whole number, we find:
\[ \text{Days needed} \approx 47 \text{ days} \]
Thus, the answer is 47 days.
