Question

Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12

Answer 1

Answer: 5, 15

Explanation:

Given

Mr. Ramirez purchased 20 concert tickets

The total price of 20 tickets is
`\$225`

Concert ticket costs
`\$15` for adults and
`\$10` for children

suppose there are x adults and y children

`\therefore x+y=20\quad \ldots (i)\\\\\Rightarrow 15x+10y=225\quad \ldots(ii)`

Solving (i) and (ii) we get

`x=5,\ y=15`

So, there are 5 adults and 15 children
