Question

The teacher distributes ${}^{\prime }{s}^{\prime }$ sheets of graph paper to each student. The class has $2b$ boys and $3g$ girls. What is the expression for the total number of sheets of graph paper distributed?

• A. $2s+3sg$
• B. $2sg+3sb$
• C. $2sb+3sg$
• D. $2sb+3g$
• E. All of the above.

Answer 1

The correct option is C $2sb+3sg$

Each student gets $s$ graph paper.
There are $2b$ boys and $3g$ girls.

$\Rightarrow$ Total class size $=$ Number of boys $+$ Number of girls
$=2b+3g$

$\Rightarrow$ Total number of graph sheets distributed
$=$ Total class size $\times$ Number of graph sheets distributed to each student
$=(2b+3g)\times s$
$=2sb+3sg$
