Question

Let prices of a pencil and an eraser be $x$ and $y$ respectively, then the algebraic expression for the price of 3 pencils and 2 erasers is _______.

• A. $3x+2y$
• B. $2x+3y$
• C. $6xy$
• D. $xy+6$

Answer 1

The correct option is A $3x+2y$

Since prices of a pencil and an eraser are $x$ and $y$ respectively,
price of 3 pencils = 3$\times$$x$ = $3x$,
price of 2 erasers = 2$\times$$y$ = $2y$,
total price = $3x+2y$.
