    50 hours

    Explanation:

    Let x represents the number of hours that Kendra needs to work

    She gets $6 for one hour so for x hours

    6x

    She already have $50 so add it

    6x + 50

    She wants to have a total of $350 so equation becomes

    6x + 50 = 350

    Now lets solve this equation

    6x = 350 - 50

    6x = 300

    x = 300/6

    x = 50 hours

    So Kendra have to babysit for 50 hours so that she can buy a new phone for $350
