Answer:

number of ounces in the third box = 32 ounces

Step-by-step explanation:

The number of ounces is directly proportional to the cost

Let O represent the number of ounces, C represent the cost

O∝C----------------Eqn 1

O = KC

K = O÷C = 20/5 = 4

Hence number of ounces in the third box = 4 × 8 = 32 ounces
