Question

S son,

Answer 1

Answer:

41 adults

Explanation:

The number of adults in the funfair is 123.

The number of children will be

$2 \times 123 = 246$

Let the number of adults and children who left the funfair be y.

This made the number of children

became four times the number of adults at the funfair.

$4(123 - y) = 246 - y$

Expand the parenthesis to get:

$492 - 4y = 246 - y$

$- 4y + y = 246 - 492$

Simplify to get:

$- 3y = - 246$

Divide both sides by -3

$y = \frac{ - 246}{ - 3} = 82$

The number of adults in the end will be:

$123 - 82$

$= 41$

There are 41 adults left
