Answer:
[tex]y=1.94x[/tex]
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 [tex]y[/tex] be the cost of the glue sticks, and [tex]x[/tex] be the number of glue sticks; then
[tex]\boxed{y=1.94x}[/tex]
We can use this equation to find the cost of 13 glue sticks; we just put [tex]x=13\[/tex] into our equation and it gives:
[tex]y=1.94(13)=25.22[/tex]
So 13 glue sticks cost $25.22.
