#### Answer

The number of beers sold was 400.
The number of sodas sold was 250.

#### Work Step by Step

Let x represent the number of beers sold. Thus, 650 - x represents the number of sodas sold.
We set up the proportion and solve by finding the cross products.
$\frac{8}{5}$ = $\frac{x}{650 - x}$
8 $\times$ (650 - x) = 5 $\times$ x
5200 - 8x = 5x
5200 = 13x
Divide both sides by 13.
x = 400
The number of beers sold was 400.
The number of sodas sold was 650 - 400 = 250.
