Answer:
\(y=1.94x\)
13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let \(y\) be the cost of the glue sticks, and \(x\) be the number of glue sticks; then
\(\boxed{y=1.94x}\)
We can use this equation to find the cost of 13 glue sticks; we just put \(x=13\\) into our equation and it gives:
\(y=1.94(13)=25.22\)
So 13 glue sticks cost $25.22.
