    Answer: 190 streetlights.

    A city currently has 122 streetlights

    They add 2 additional streetlights at end of each week for 52 weeks:

    Additional streetlights=2x52

    =104

    104 streetlights/52 weeks=x/34 weeks

    x=34x104/52

    =3536/52

    =68 streetlights

    The city has 68 additional streetlights after 34 weeks now you have to add it to the current amount to find how much they'll have in total:

    Current amount+additional amount=122+68

    =190 streetlights

    The city has 190 streetlights after 34 weeks.
