At the grocery store, you buy a carton of milk for $1.95, a loaf of bread for $0.85, and a box of cereal for 92.05. Use mental math to find the total cost of the groceries.

Answer 1

To find the total cost of the groceries, let's break it down into smaller parts using mental math. Here are the prices of the items you purchased:

- Milk: $1.95
- Bread: $0.85
- Cereal: $92.05

First, add the prices of the milk and the bread:

\[ 1.95 + 0.85 \]

Consider the whole numbers and the decimal parts separately:

Whole numbers: \( 1 + 0 = 1 \)
Decimal parts: \( 0.95 + 0.85 \)

Breaking down the decimal addition:

\[ 0.95 + 0.85 = 1.80 \]

Now, combine the whole number with the decimal sum:

\[ 1 + 1.80 = 2.80 \]

Next, add this result to the price of the cereal:

\[ 2.80 + 92.05 \]

Combine the whole numbers first:

\[ 2 + 92 = 94 \]

Now add the decimal parts:

\[ 0.80 + 0.05 = 0.85 \]

Combine these results to get the total cost:

\[ 94 + 0.85 = 94.85 \]

So, the total cost of the groceries is:

\[ \boxed{94.85} \]
