Question

A grocery store sells salmon fillets in package that contains at least 3 fillets of salmon,but no more than 5.which of the following could be the total number of salmon fillets in 6 packages

Answer 1

Answer: 18 ≤ 6*S ≤ 30

Where S is the number of salmon fillets in one single package.

Explanation:

Let's define S as the number of salmon fillets in one package.

We know that it contains at least 3, and no more than 5, then we can write:

3 ≤ S ≤ 5

Now we want to know the total number of salmon fillets that could be on 6 packages, then if S is the number of salmon fillets in one package, 6*S will e the number of salmon fillets in 6 packages.

We can find this by multiplying the inequality:

3 ≤ S ≤ 5

by 6.

We get:

6*3 ≤ 6*S ≤ 6*5

18 ≤ 6*S ≤ 30

Then in 6 packages, we could have any number between 18 and 30 fillets of salmon.
