Answer:
50% increase
Step-by-step explanation:
120 - 80 = 40
40 = 50% of 80
The volume of the box is
.. V = (90 cm)*(45 cm)*(45 cm) = 182,250 cm³
The empty 15% of the volume is then
.. empty volume = 0.15*182,250 cm³ = 27,337.5 cm³
This will require
.. (empty volume)/(volume / bag) = 27,337.5 cm³ / (28,316 cm³/bag) ≈ 0.97 bag
to fill.
Selection A. 1 bag is appropriate.
Answer:
About $118.70
Step-by-step explanation:
139 x .2 = 27.8
139 - 27.8 = 111.2
111.2 x .0675 = 7.5
111.2 + 7.5 = 118.7
118.7 = $118.70
So the teacher bought 1/4 of the brownie pan. And it came out to $4.
I hope this helps! :)
