You wish to mentally estimate the total cost of items that have the following prices: $1.85, $.98, $3.49,
$9.78, and $6.18. Rounding off the items to the nearest half-dollar, your estimate of the total cost of these
items is
A. $22.50.
B. $22.30.
C. $22.59.
D. $23.00.
Is it A??
Right.
$22.50
To mentally estimate the total cost, you can round each price to the nearest half-dollar and then add them up.
$1.85 rounds to $2.00
$0.98 rounds to $1.00
$3.49 rounds to $3.50
$9.78 rounds to $10.00
$6.18 rounds to $6.00
Now, add up the rounded prices:
$2.00 + $1.00 + $3.50 + $10.00 + $6.00 = $22.50
Therefore, the estimated total cost is $22.50. So, your answer is A.
To mentally estimate the total cost of these items, you can round each price to the nearest half-dollar and then add them up.
Let's round each price to the nearest half-dollar:
$1.85 rounds to $2.00
$.98 rounds to $1.00
$3.49 rounds to $3.50
$9.78 rounds to $9.50
$6.18 rounds to $6.00
Now, add up these rounded prices:
$2.00 + $1.00 + $3.50 + $9.50 + $6.00 = $21.00
So, the estimated total cost is $21.00.
None of the given answer choices match the estimated total of $21.00. Therefore, the correct answer is not provided in the options provided.
