Assuming she got 2kg of oranges at $1.99/kg, 3kg of bananas at $2.75/kg and 5kg of apples at $2.15/kg...

For 2kg of oranges she spent
1.99×2= $3.98

For 3kg of bananas she spent
2.75×3= $8.25

For 5kg of apples she spent
2.15×5= $10.75

3.98+8.25+10.75= $22.98
She spent $22.98 in total.

30-22.98= $7.02
She received $7.02 in change.
