    Answer:37 and half hrs

    Step-by-step explanation:

    This is what I get

    Myra: 50/2 = 25 bulbs/hr.

    Francis: 45/3 = 15 bulbs / hr

    25+15 = 40/hr. Together per hr

    Need to find 150 bulbs how many hrs

    40/1=150/t

    40t=150

    T = 150/4

    T = 37.5

    37hrs and 1/2
