Explanation:
Part 1: She spent $3.42 on the folders.
This is calculated by multiplying 6 folders by $0.57 for each folder
($0.57 x 6 = $3.42).
Part 2: She will receive $6.58 in change. This is calculated by subtracting the amount spent on the folders from the amount of money Gi Gi had to begin with ($10 - $3.42 = $6.58).
