Question

Solomon buys $x$ number of pizzas and $y$ number of burgers from a restaurant. Charles buys twice the number of pizzas and one less burger than Solomon. Which of the following algebraic expressions represents the total order of Charles?

• A. $2x-(y+1)$
• B. $2x+(y+1)$
• C. $x+(y-1)$
• D. $2x+(y-1)$

Answer 1

The correct option is D $2x+(y-1)$

Number of pizzas Solomon buys $=x$
Number of burgers Solomon buys $=y$

The number of pizzas Charles buys is twice that of Solomon. Number of pizzas Charles buys $=2x$

The number of burgers Charles buys is one less than that of Solomon, which is equal to $y-1$.

Total order of Charles = number of pizzas bought by Charles + number of burgers bought by Charles $=2x+(y-1)$
