    Answer:

    • B. 308

    Step-by-step explanation:

    • Table is given below
    • Find the missing values.
    • The one we are looking for is total of green = y.

                     |              1 -H        |       2-H          |       Total

    Green       |           170            |          x           |       y      

    Purple       |            z              |       284          |       w        

    Total         |            430          |          v            |      852      

    • z = 430 – 170 = 260
    • w = 260 + 284 = 544
    • y = 852 – 544 = 308
    • v = 852 – 430 = 422

    Correct choice is B
