Respuesta :

Using proportions, it is found that:

  • The ratio in this history is [tex]\frac{a}{y} = \frac{8}{5}[/tex]
  • Altogether, 390 tickets were sold to last night's game.

What is a proportion?

  • A proportion is a fraction of total amount, and is also related to ratios.
  • A ratio of two amounts a and b is given by a divided by b.

They sold 8 adult tickets for every 5 youth tickets, hence the ratio between a(the number of adult tickets sold) and y(the number of youth tickets sold) is:

[tex]\frac{a}{y} = \frac{8}{5}[/tex]

150 youth tickets were sold, hence the number of adult tickets sold was of:

[tex]a = \frac{8}{5}y = \frac{8}{5}(150) = 240[/tex]

Then, in total, 150 + 240 = 390, hence:

Altogether, 390 tickets were sold to last night's game.
