Respuesta :
Total number of pizzas Juan ordered [tex]20[/tex]
Since, [tex]45\%[/tex] of pizzas have [tex]8[/tex] slices.
Therefore, number of pizzas with [tex]8[/tex] slices are: [tex]45\%\times(20)[/tex]
[tex]=\frac{45}{100} \times(20)[/tex]
[tex]=\frac{45}{10} \times(2)[/tex]
[tex]=\frac{90}{10}[/tex]
[tex]=9[/tex] pizzas
Also, since, [tex]55\%[/tex] of pizzas have [tex]12[/tex] slices.
Therefore, number of pizzas with [tex]12[/tex] slices are: [tex]55\%\times(20)[/tex]
[tex]=\frac{55}{100} \times(20)[/tex]
[tex]=\frac{55}{10} \times(2)[/tex]
[tex]=\frac{110}{10}[/tex]
[tex]=11[/tex] pizzas
Now, there are [tex]9[/tex] pizzas with [tex]8[/tex] slices and [tex]11[/tex] pizzas with [tex]12[/tex] slices.
Therefore, total number of slices of pizza are: [tex]=(9)(8)+(11)(12)[/tex]
[tex]=72+132[/tex]
[tex]=204[/tex] slices
