Question

Ben harvested $962$ corn cobs from his farm. He gave $254$ corn cobs to Amy. Out of the remaining corn cobs, he gave $359$ corn cobs to Stacy. How many corn cobs are left with Ben?

• A. $239$
• B. $349$
• C. $419$
• D. $329$

Answer 1

The correct option is B $349$

Given, Ben harvested $962$ corn cobs from his farm and gave $254$ corn cobs to Amy.
So, the number of corn cobs remaining $=962-254$

Let’s represent each of these numbers based on their place value and subtract them.
$962$ can be decomposed as $900+60+2$.
$254$ can be decomposed as $200+50+4$.


So, $708$ corn cobs are left.

Ben also gave $359$ corn cobs to Stacy.
So, the number of corn cobs left with Ben in the end $=708-359$

Let’s represent each of these numbers based on their place value and subtract them.
$708$ can be decomposed as $700+0+8$.
$359$ can be decomposed as $300+50+9$


So, $349$ corn cobs are left with Ben.
