Total amount spent by the three friends

=$3.30+$9.90+$7.90

=$21.10

Answer:

1. $21.10

2. $2.10

Step-by-step explanation:

"Three siblings go to the school fair"

"What was the total money spent by the three friends at the school fair?"

I will assume that the three siblings are the same people as the three friends.

1.

Amount spent by each one:

Sidney: $3.30

Koi: 3 * $3.30 = $9.90

Daisy: $9.90 - $2 = $7.90

Total amount spent by all 3: $3.30 + $9.90 + $7.90 = $21.10

Total amount spent: $21.10

2.

They evenly split $30.

$30/3 = $10

Each one had $10 to spend.

Daisy spent $7.90 out of the $10 she had.

The amount left for Daisy is: $10 - $7.90 = $2.10
