50. Karen went to the grocery store with $40. She bought a carton of milk for $1.85, a loaf of bread for $3.20, and a bunch of bananas for $3.05. How much money does she have left?
Answer: B
Karen has $31.90 left.
After purchasing the items, Karen spent a total of $8.10, which leaves her with $31.90 from her initial $40.
A) $30.95
This option is incorrect because it does not accurately reflect the total amount Karen has left after her purchases. If she were to have $30.95 left, it would imply she spent $9.05, which is higher than the actual total spent of $8.10.
B) $31.90
This is the correct answer as it correctly calculates the remaining amount after accounting for the total spent. Karen started with $40 and spent $8.10, resulting in $31.90 remaining.
C) $32.10
This option is incorrect because it suggests that Karen has $32.10 left after spending $8.10. If this were true, she would have only spent $7.90, which does not match the total cost of her purchases.
D) $34.95
This option is incorrect as it indicates that Karen has $34.95 left. This would imply she only spent $5.05, which is significantly less than her actual total expenditure of $8.10.
Conclusion
The correct answer, $31.90, accurately reflects the amount Karen has left after her purchases. The other options fail to account for the correct total spent, leading to incorrect remaining balances. Thus, only option B aligns with the calculations based on her initial amount and total purchases.
