Question

A​ 0.8-liter bottle of Mexican wine costs 101 pesos. At that​price, how much would a​ half-gallon jug of the same wine cost in​dollars?

Answer 1

$12.18

Explanation:

Given:

Cost of 0.8 liter bottle of Mexican wine = 101 pesos

or

cost of 1 liter bottle of Mexican wine =
`\frac{\textup{101}}{\textup{0.8}}` pesos

Now,

1 Mexican pesos = 0.051 dollars

thus,

cost of 1 liter bottle of Mexican wine =
`\frac{\textup{101}}{\textup{0.8}}*0.051` dollars

also,

1 gallon = 3.78541 Liter

Thus,

half gallon =
`\frac{\textup{3.78541}}{\textup{2}}` = 1.892705 Liters

therefore,

cost of half gallon jug =
`\frac{\textup{101}}{\textup{0.8}}*0.051*1.892705` dollars

or

cost of half gallon jug of wine = $12.18
