a) f(n) = 11 + f(n - 1)
Step-by-step explanation:
f(2) = 11 + 4 = 15

f(5) = 11 + 37 = 48
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.
