Mentally estimate the total cost of items that have the following prices: $1.85, $.98, $3.49, $9.78, and $6.18. Round off your answers to the nearest half-dollar. A. $22.59 B. $22.30 C. $22.50 D. $23.00

Answer: Option (c) is correct.

Explanation:

Given that,

Round off the values of items to the nearest half dollar are as follows:

Item 1 = $2.00

Item 2 = $1.00

Item 3 = $3.50

Item 4 = $10.00

Item 5 = $6.00

Estimated total cost of items = Item 1 + Item 2 + Item 3 + Item 4 + Item 5

= $2.00 + $1.00 + $3.50 + $10.00 + $6.00

= $22.50

Hence, nearest value is $22.50.

Therefore, option (c) is correct.
