Question

19 glue sticks cost $7.47Write and solve an equation that would help determine the cost of 2 gluesticks?

Answer 1

Given data:

The expression for the cost of 19 glue sticks is 19g= $7.47.

The given expression can be written as,

$\begin{gathered} 19\text{ g=\ 7.47} \\ 1\text{ g=\ }\frac{7.47}{19} \end{gathered}$

Multiply the above expression by 2 on both sides.

$\begin{gathered} 2\text{ g =2(\ }\frac{7.47}{19}) \\ =0.786 \end{gathered}$

Thus, the cost of 2 glue sticks is $0.786.
