Final answer:
Jessica will spend $8.59 on 2 sandwiches and 3 drinks.
Step-by-step explanation:
To find out how much Jessica will spend on 2 sandwiches and 3 drinks, we can use the information from Lucy and Melissa's purchases as a reference.
From the given information, we know that Lucy bought 3 sandwiches and 2 drinks for $9.50, and Melissa bought 4 sandwiches and 2 drinks for $12.00. Let's calculate the cost per sandwich and per drink from these two purchases.
The cost per sandwich for Lucy is $9.50 divided by 3, which equals $3.17. The cost per sandwich for Melissa is $12.00 divided by 4, which equals $3.00.
The cost per drink for both Lucy and Melissa is $9.50 minus the cost of sandwiches, divided by 2, which equals $0.75.
Now, we can calculate the total cost for Jessica's 2 sandwiches and 3 drinks.
The cost of 2 sandwiches will be 2 multiplied by the cost per sandwich ($3.17), which equals $6.34.
The cost of 3 drinks will be 3 multiplied by the cost per drink ($0.75), which equals $2.25.
So, the total cost for Jessica's purchase will be $6.34 (for sandwiches) plus $2.25 (for drinks), which equals $8.59.
