Respuesta :

Answer:

The total number of questions are 40

Step-by-step explanation:

let the total number of questions be "x".

percent of questions answered correctly are 80.

In fractions 80% is [tex]\frac{4}{5}[/tex]

The total number of correctly answered questions are 32.

the equation is,

[tex](\frac{4}{5})(x) = 32[/tex]

thus , x = [tex]\frac{(5)(32)}{4}[/tex]

x= 40
