    no n 16

    Step-by-step explanation:

    cost for 3 pencils, a hat, and 2 binders

    = 3*0.3+14.5+2*3.2

    = $21.8 > $20

    so estimate not good

    5/0.3=16.6 ...

    so she can buy 16 pencils

    Step-by-step explanation:

    Yes, her estimate is not good because one hat is $14.50 and 2 binders are$3.20*2=^$6.40. Those two items combined is over $20. The pencils will put the total further over $20.

    Pencils are $0.30 each. So 10 pencils will cost $3.

    $5 - $3 = $2

    The remaining $2 is enough for 6 more pencils.

    So she could buy 10+6 = 16 pencils with $5.
