1. Karen goes to the grocery store with $40. She buys 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 her purchases.
After purchasing a carton of milk for $1.85, a loaf of bread for $3.20, and a bunch of bananas for $3.05, Karen has $31.90 remaining from her initial $40.
A) $31.90
This option is presented twice in the question, but it is correct. The calculations show that $1.85 + $3.20 + $3.05 equals $8.10. Subtracting this amount from $40 leaves Karen with $31.90.
B) $31.90
This option is also correct and identical to option A. It confirms that after spending $8.10 on her groceries, Karen has $31.90 left, which matches the calculated remainder.
C) $32.10
This option is incorrect. If Karen had $32.10 left, it would imply she spent only $7.90 on her groceries, which contradicts the total amount spent of $8.10.
D) $34.95
This option is incorrect as well. If Karen had $34.95 remaining, it would mean she only spent $5.05 on her groceries, which is not consistent with the actual total of $8.10.
Conclusion
The correct answer is $31.90, supported by the accurate calculations of Karen's total expenditure. All other options misrepresent the amount spent or remaining, highlighting the importance of precise arithmetic in solving such problems.
