x  the number of boots
y  the number of sandals
The ratio of boots to sandals is 8:3.
[tex]\frac{x}{y}=\frac{8}{3} \\ 8y=3x \\ y=\frac{3}{8}x[/tex]
There are 245 more boots than sandals.
[tex]y+245=x \\ y=x245 \\ \\ y=y \\ \frac{3}{8}x=x245 \\ \frac{3}{8}xx=245 \\ \frac{3}{8}x\frac{8}{8}x=245 \\ \frac{5}{8}x=245 \\ x=245 \times (\frac{8}{5}) \\ x=49 \times 8 \\ x=392[/tex]
There are 392 boots.
