Question

Harry is in a line at the store. He has 3 items that cost $5.95, $4.25, and $1.05. Explain how harry can add the cost of the items mentally before he pays for them

Answer 1

Harry has $11.25 because (5+4)+1=10 and 95+5=100 and 100 cents converted into dollars is $1.00+25 and now Harry has $11.25

Answer 2

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
