Question

On his birthday, Robert received 79 chocolates. He ate six of them before giving three to her sister, and after sharing two chocolates to each of his 27 friends, he was left with $x$ number of chocolates.
Derive an algebraic expression for $x$ from the above comprehension

• A. $79-6-3+54=x$
• B. $79-6-3-54=x$
• C. $79+6+3+54=x$
• D. $79+6+3+54=-x$

Answer 1

The correct option is A $79-6-3+54=x$

The total number of chocolate = 79.

Number of chocolates ate by Robert $=6$

Number of chocolate ate by her sister $=3$

Number of chocolate ate by 25 friends$=2\times 27=54$

Number of chocolate remaining after distribution $=x$

Total number of chocolate - Number of chocolate ate by Robert - Number of chocolate ate by her sister - Number of chocolate ate by 25 students = Number of chocolate remaining after distribution
$\Rightarrow 79-6-3-54=x$
