Question

389 dollars were spent on a fork set and half of this amount was spent on 2 spoon sets. Find the estimated cost of each spoon set. (Round off the inital amount to the nearest hundred.)

• A. 400 dollars
• B. 200 dollars
• C. 100 dollars
• D. 300 dollars

Answer 1

The correct option is C 100 dollars

389 can be rounded off to 400.
So, amount spent on Fork set = 400 dollar
Amount spent on 2 spoon sets
$=\frac{1}{2}\times \text{Amount spent on Fork set}$
i.e. $400÷2=200$ dollar

Amount spent on 1 spoon set
= $200÷2=100$ dollar

Thus, the estimated cost of each spoon set is 100 dollar.
