Help my sister please she needs help I don’t know because I forgot

Answer:
15 shrimps
Step-by-step explanation:
We already know that a small shrimp taco has 5 shrimps.
⇒ [tex]\text{1st equation: small shrimp taco = 5 shrimps}[/tex]
We also know that a large taco has 3 times more shrimps than a small taco.
⇒ [tex]\text{2nd equation: shrimps in a large taco = 3(Shrimps in a small taco)}[/tex]
Finding the number of shrimps in a large taco:
Now, simply substitute the number of shrimps in a small shrimp taco in the second equation to find the number of shrimps in a large taco.
