Answer:
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.
1/2 foot is 6 inches.
Brenda has to divide that 6 inches up into slices that are 2/3 inch thick.
If she uses a saw that has no thickness and makes no sawdust, she can get
(6) ÷ (2/3) = (6) · (3/2) = (18 / 2) = 9 slices out of the 6-inch post.
