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.
