Use the main ratio to find how many of each toy, then apply the sub-ratios.<br><br>
&bull; Dolls : Cars = 5 : 8, total 130 toys.<br>
&bull; Dolls = \(\frac{5}{13} \times 130 = 50\); Cars = \(\frac{8}{13} \times 130 = 80\).<br>
&bull; Plastic dolls = \(\frac{3}{3+2} \times 50 = \frac{3}{5} \times 50 = 30\).<br>
&bull; Plastic cars = \(\frac{5}{5+3} \times 80 = \frac{5}{8} \times 80 = 50\).<br>
&bull; Total plastic toys = 30 + 50 = 80.<br><br>
Final Answer: 80
