Question

At the grocery store you choose to buy 4 items that cost: $2.69, $14.45, $8.05, and $13.95. Estimate the total cost of your groceries by rounding the cost of each item to the nearest dollar. What is the estimated total?

Answer 1

$39

Explanation:

First, let's get the values of each number by rounding them off to the nearest dollar before adding them.

• Remember that you have to round off the number up if it is being followed by a number equivalent to 5 and above. You have to retain the number if it is followed by a number less than 5.

1. $2.69 = $3

2. $14.45 = $14

3. $8.05 = $8

4. $13.95 = $14

Now that you have the rounded off numbers, you may add them.

Let's solve.

• $3 + $14 + $8 + $14 = $39

The estimated total is $39.
