Sagot :

Answer: 5, 15

Step-by-step explanation:

Given

Mr. Ramirez purchased 20 concert tickets

The total price of 20 tickets is [tex]\$225[/tex]

Concert ticket costs [tex]\$15[/tex] for adults and [tex]\$10[/tex] for children

suppose there are x adults and y children

[tex]\therefore x+y=20\quad \ldots (i)\\\\\Rightarrow 15x+10y=225\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

[tex]x=5,\ y=15[/tex]

So, there are 5 adults and 15 children
