Let's calculate the total cost of lunch for Andrew and Olivia step by step.

  1. Sandwich: $6.99
  2. Bag of pretzels: $2.25
  3. Juice: $2.36

Now, we'll add these amounts together:

\[ 6.99 + 2.25 + 2.36 \]

Calculating this step by step:

  1. First, add $6.99 and $2.25:

\[ 6.99 + 2.25 = 9.24 \]

  1. Next, add $2.36 to $9.24:

\[ 9.24 + 2.36 = 11.60 \]

So the total for each person is $11.60.

  • Andrew calculated a total of $11.60, which is correct.
  • Olivia calculated a total of $11.6, which is also effectively the same amount, as $11.60 is equivalent to $11.6.

Therefore, since both totals represent the same amount, the answer is:

A. Both Andrew and Olivia
