Mixed applicationsDuring the month of July 3/20 of the tshirts sold were small and 10/25 of the T-shirt’s sold were size large. What percent of the tshirts sold were neither small or large?

Respuesta :

Let x be the fraction that corresponds to the percent of T-shirts sold that were neither small nor large, then:

[tex]x+\frac{3}{20}+\frac{10}{25}=1.[/tex]

Adding like terms we get:

[tex]x+\frac{11}{20}=1.[/tex]

Subtracting 11/20 from the above equation we get:

[tex]x=1-\frac{11}{20}=\frac{9}{20}\text{.}[/tex]

The above fraction as a percentage is

[tex]\frac{9}{20}\times100=45.[/tex]

Answer: 45%.
