Answer:$98.15
Step-by-step explanation:
Lorraine Bought 7500/25 = 300 ml of Milk = 0.3 litres.
20.5*0.3 = $6.15
Also, She Bought 3 litres 500 ml = 3.5 litres of cooking oil.
110.20*3.5 = $385.7
385.7 + 6.15 = $391.85
The Amount She Got Back = 500 - 391.85 = $108.15
She Gave : $ 10.
108.15 - 10 = $98.15
