Solution

The correct option is C $22,000
Price of the bed = $12,354

Price of the sofa = $9,650

Estimating follows the given rules:

i. If the deciding digit < 5, then round down.

ii. If the deciding digit > 5, then round up.

iii. If the deciding digit = 5, then round up.

Total cost = Sum of prices of the bed and the sofa

= 12,354 + 9,650

Rounding the numbers to the nearest thousands, we get:

= 12,000 + 10,000

Adding the rounded numbers, we get:

So, the estimated price for both items is $22,000.
