Julli [10]

Answer:

The system of equations in standard form is equal to

11a+19b=71

a+b=5

The number of ounces of perfume A is 3\ ounces

The number of ounces of perfume B is 2\ ounces

Step-by-step explanation:

Let

a-----> the number of ounces of perfume A

b----> the number of ounces of perfume B

we know that

11a+19b=71 -----> equation A

a+b=5

a=5-b -----> equation B

substitute equation B in equation A and solve for b

11(5-b)+19b=71

55-11b+19b=71

8b=71-55

8b=16

b=2\ ounces

Find the value of a

a=5-b -----> a=5-2=3\ ounces
