Answer:
2340
Step-by-step explanation:
3 3/4=15/4 3 1/4=13/4 turn the mixed fractions into improper fractions
(15/4)(3)(13/4)=36.5625ft³ this is the volume of the shipping box
(1/4)(1/4)(1/4)=1/64ft³ this is the volume of the fish food box
36.5625/(1/64) divide it to find out how much fish boxes can fit
36.5625×64 flip the fraction and multiply
2340

50% off
Step-by-step explanation:
Check the picture below.
so.. notice, the box for the gift is really just a rectangular prism, which is really just 6 rectangles stacked up to each other at the edges.
the front and back are two 5x3 rectangles
the left and right are just two 3x7 rectangles
and the top and bottom are just two 5x7 rectangles
so, just get the area of each, sum them up, and that's the area of the rectangular prism and thus of the box, and that's how many in² she will need.
We have that
<span> 5x/7=22
multiply by 7 both sides
5x=22*7-------> 5x=154
divide by 5 both sides
x=154/5
x=30.8--------> x=30 4/5
the answer is
x=30 4/5</span>
Divide it and get 0.6 then multiply by 100 so 60%
