help me asap this is from ka its super easy

Answer:
[tex]\boxed{\tt \cfrac{4}{\$ 7.76} =\cfrac{13}{x} }[/tex]
Step-by-step explanation:
4 glue sticks cost $7.76.
[tex]\dashrightarrow \tt \cfrac{4}{\$\:7.67}[/tex]
let x represent the cost of 13 glue sticks. and now since 13 glue sticks cost x, we have the following proportion:
[tex]\dashrightarrow\tt \cfrac{13}{x}[/tex]
Cost changes along with the number of glue sticks purchased, and so the two proportions are equivalent.
[tex]\dashrightarrow\tt \cfrac{4}{\$ 7.76} =\cfrac{13}{x}[/tex]
Therefore, your answer is C !!!!!
