2、A prize fund is divided into first, second, and third prizes. The prize for each first prize is twice that of each second prize, and the prize for each second prize is twice that of each third prize. If one, two, and three winners are awarded for first, second, and third prizes respectively, then the prize for each first prize is 308 yuan; If one first prize, two second prizes, and three third prizes are awarded, what is the prize for the first prize in yuan?
2.【Solution】The total amount of the bonus is: $308 \times\left[\left(1+\frac{1}{2}+\frac{1}{4}\right) \times 2\right]=1078$ (yuan)

Distributed as one first prize, two second prizes, and three third prizes, the first prize is: $1078+(1$
$$
\left.+\frac{1}{2} \times+\frac{1}{4} \times 3\right)=392 \text { (yuan) }
$$
