Answer: It is explained below
Explanation:
Harry is in a line at the store and he has 3 items that cost $5.95, $4.25, and $1.05. To add them mentally, he can approximate each item. This will be:
$5.95 = $6
$4.25 = $4
$1.05 = $1
So by adding the approximated amount, he will have:
$6+$4+$1 = $11
So, mentally he'll know he has about $11 to pay.
The real cost of the 3 items is:
$5.95 + $4.25 + $1.05 = $11.25
