The number of cars manufactured in the US is 8086 per day. The number of cars manufactured in Germany is 16172 per day.

#### Work Step by Step

Let $u$ be the number of cars manufactured in the US. The number of cars manufactured in Germany is $2u$. $u+2u=24258$ $\longrightarrow$combine like terms $3u=24258$ $\longrightarrow$multiplication property $3u\div3=24258\div3$ $\longrightarrow$simplify $u=8086$ $2u=2\times8086=16172$
