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=\$}(7.47)/(19) \end{gathered}`

Multiply the above expression by 2 on both sides.

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

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