Adelia had 4 dollars. She found 50 cents then bought a snack. She ended up with 6 quarters.

Answer: Adelia brought a snack that costed 3 dollars.

Step-by-step explanation:

4 quarters in each dollar

(4dollars*4quarters)

$4.00=16 quarters

(she found 2 more quarters)

16+2=18

0.25*18 = $4.50

She brought a snack that left her with 6 quarters ($1.50)

$4.50-$1.50=$3.00

Adelia brought a snack for $3.00
