Final answer:
After spending $2.40 daily on lunch for 15 days, Sabra will have $99 remaining from her initial $135.
Step-by-step explanation:
The question involves a straightforward arithmetic calculation related to personal finance. Sabra spends $2.40 each day on lunch and has $135 at the beginning. To find out how much she will have left after 15 days, we multiply her daily spending by the number of days:
Daily spending = $2.40
Number of days = 15
Total spent after 15 days = Daily spending × Number of days
Total spent after 15 days = $2.40 × 15
Total spent after 15 days = $36
After calculating the total amount spent on lunch over 15 days, we subtract this amount from her initial funds:
Initial amount = $135
Total future amount after 15 days = Initial amount - Total spent after 15 days
Total future amount after 15 days = $135 - $36
Total future amount after 15 days = $99
Therefore, Sabra will have $99 remaining after 15 days, assuming she continues to spend $2.40 each day on lunch without any additional expenditures or income.
