Andrew and Olivia buy lunch. They each get

Question

a sandwich for $6.99,
a bag of pretzels for $2.25, and
a juice for $2.36.
Andrew calculates the total by hand and gets $11.60 for his lunch. Olivia uses a calculator and gets a total of $11.6 for her lunch.

Who is correct?

Answer 1

Let's break down the total cost of Andrew and Olivia's lunch step by step.

1. Cost of sandwich: $6.99
2. Cost of bag of pretzels: $2.25
3. Cost of juice: $2.36

Now, we can add these amounts together:

\[ \begin{align*} 6.99 \

• 2.25 \
• 2.36 \ \end{align*} \]

Now let's perform the addition:

1. Adding the first two items: \[ 6.99 + 2.25 = 9.24 \]

2. Now add the juice: \[ 9.24 + 2.36 = 11.60 \]

Thus, the total cost of the lunch for each person is $11.60.

Both Andrew, who calculated $11.60, and Olivia, who got $11.6, are actually correct. The two representations are the same (11.60 and 11.6 are equivalent).
