Final answer:
To find the cost for Jessica to buy 2 sandwiches and 3 drinks, we can calculate the cost per sandwich and drink using the information given. Then we can multiply the cost per item by the quantity desired and sum them up to find the total cost. The correct answer is $15.34.
Step-by-step explanation:
To find out how much it will cost Jessica to buy 2 sandwiches and 3 drinks, we can start by finding the cost of each sandwich and drink.
Based on the information given, we know that Lucy bought 3 sandwiches and 2 drinks for $9.50, and Melissa bought 4 sandwiches and 2 drinks for $12.00.
So, the cost per sandwich for Lucy is $9.50 / 3 = $3.17, and for Melissa it's $12.00 / 4 = $3.00.
Since Jessica wants to buy 2 sandwiches and 3 drinks, the total cost for her would be (2 sandwiches x $3.17) + (3 drinks x $3.00) = $6.34 + $9.00 = $15.34.
Therefore, the correct answer is $15.34.
