Verified Answer :

  1. 20% means 20/100 or 2/10
    so 2/10 of 1000=spanish=200=spanish


    2.6%=6/100
    6/100 times 1000=60


    3. so 12%of 6th graders=24
    divide by 6
    2%of 6th graders=4
    multiply by 50
    100%of 6th graders=200
    200 6th graders

    4. so 5%=5/100=0.05
    so tax=13.75 times 0.05=0.69
    tax=69 cents
    13.75+0.69=14.44
