Answer 1

Answer:

97 adults and 151 children assisted to that show.

Step-by-step explanation:

We are gonna use "dollars" instead of "soles.

According to the problem, tickets cost $30 for adults and $20 for children.

Last Saturday assisted 248 people which gave a total of $5930.

To know the number of adults and children were there, we need to defined a system of equations.

$x+y=248\\30x+20y=5930$

Where $x$ represents adults and $y$ represents children.

First, we multiply the first equation by -20

$-20x-20y=-4960$

Then, we sum this equation with the second one

$10x=970\\x=97$

There were 97 adults.

Now, we use this value to find the other one

$x+y=248\\97+y=248\\y=248-97\\y=151$

There were 151 children.

Therefore, 97 adults and 151 children assisted to that show.
