Question 836945
Basil - 6.20 per ounce

Set ounces of basil = x
Total value of basil = 6.2x


Oregano - 3.70 per ounce

Set ounces of Oregano = y
Total value of Oregano = 3.7y

x + y = 20 ounces total

6.2x + 3.7y = 5.2(20)

x + y = 20; x = 20 - y

6.2(20 - y) + 3.7y = 104

124 - 6.2y + 3.7y = 104

124 - 2.5y = 104

-2.5y = -20

y = 8 ounces of Oregano
x = 20 - y = 12 ounces of Basil

CHECK:

8 + 12 = 20 ounces total

8(3.7) + 12(6.2) = 20(5.2) 
104 = 104; Correct
