To determine how many apples Ellen can buy next week, we first need to find out the cost per apple based on her previous purchases.
-
For last week:
- Ellen bought 4 apples for $2.40.
- Cost per apple = Total cost / Number of apples = $2.40 / 4 = $0.60 per apple.
-
For this week:
- She bought 9 apples for $5.40.
- Cost per apple = Total cost / Number of apples = $5.40 / 9 = $0.60 per apple.
The cost per apple remains consistent at $0.60.
Now, let's analyze each option to see how many apples she could buy based on different total costs:
A. 1 apple for $1.20
- This would imply a cost per apple of $1.20, which is incorrect.
B. 6 apples for $3.40
- Cost for 6 apples = 6 × $0.60 = $3.60 (not equal to $3.40).
C. 10 apples for $6.00
- Cost for 10 apples = 10 × $0.60 = $6.00 (this is correct).
D. 13 apples for $8.20
- Cost for 13 apples = 13 × $0.60 = $7.80 (not equal to $8.20).
The only option that reflects the correct cost is:
C. 10 apples for $6.00
