What is 50,000,000,000 200,000 30,000 in standard form

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.
