Question

Andrew and Olivia buy lunch. They each get

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).
