Answer:

$0.08 (rounded to nearest hundredth, 2 decimals)

Step-by-step explanation:

This is very easy if we setup a unitary method ratio.

" If 12.8 pesos equal 1 dollar, 1 peso is HOW MANY (let it be x) dollars?"

We translate the above sentence in ratio and solve for x:

[tex]\frac{Peso}{Dollar}=\frac{12.8}{1}=\frac{1}{x}\\12.8x=1\\x=\frac{1}{12.8}\\x=0.08[/tex]

Thus, it is worth about $0.08
