Sinea wants to spend money using the same ratios as on her last trip to the carnival. If she spends $28 on games, how much will she spend on souvenirs?

Snacks Games Souvenirs
Sine $5 $8 $18

28 / 8 = s / 18

To determine how much Sinea will spend on souvenirs, we can use the ratio between the amounts spent on games and souvenirs during her last trip to the carnival. According to the given information, Sinea spent $8 on games and $18 on souvenirs.

To find the ratio of games to souvenirs, we divide the amount spent on games ($8) by the amount spent on souvenirs ($18).

$8 / $18 = 4/9

This ratio can be interpreted as, for every 4 parts spent on games, 9 parts are spent on souvenirs.

Now, we can use this ratio to find the amount Sinea will spend on souvenirs if she spends $28 on games.

Let's set up a proportion:

4 / 9 = $28 / x

To solve for x (the amount spent on souvenirs), we cross-multiply:

4x = 9 * $28
4x = $252

Finally, we divide both sides of the equation by 4 to solve for x:

x = $252 / 4
x = $63

Therefore, Sinea will spend $63 on souvenirs if she spends $28 on games.
