Answer :

Answer:

z = 5x + 7y

Explanation:

If x is the number of A pills, the amount of undesired substance is 5 mg times x or

5x

In the same way, if y is the number of B pills, the amount of undesired substance is 7 mg per pill, so the total will be 7 mg times y or

7y

Then, the function that represents the amount of undesired substance will be

z = 5x + 7y
