Question

The teacher distributes $1$ sheet 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. $2b+3g$
• B. $2g+3b$
• C. $4b+3g$
• D. $2b+5g$

Answer 1

The correct option is A $2b+3g$

Each student gets $1$ graph paper.
There are $2b$ boys and $3g$ girls.
$2b+3g$ $\Rightarrow$ Total class size
Total number of students $=$ total number of boys $+$ total number of girls
Total graph sheets $=1$ $\times$ (Number of students)
$=1$ $\times$ $(2b+3g)=2b+3g$
Total number of graph sheets is equal to the class size.
