Answer:
3rd, 4th, and 5th options.
Step-by-step explanation:
The way this was formatted was a little weird, but the 3rd, 4th, and 5th options are correct I think.
If there was 358.92 left, it has to be divided 3 ways (after subtracting 451.89 - 358.92). So that means that 3c or c+c+c could be correct, as well as using dis. property to switch around the last one I guess.

Given/equations formed from text:
I: l=w+3
II: A=l*w
III: new area B=(l-2)*w
IV: B=A-30
substitute l in II with I to remove l:
II': A=l*w=
(w+3)*w=
w^2+3w
substitute l in III with I to remove l:
III': B=(l-2)*w=
(w+3-2)*w=
(w+1)*w=
w^2+w
substitute A and B from II' and III' into IV:
B=A-30
w^2+w=w^2+3w-30
30=2w
w=15
insert w=15 into I:
l=15+3=18
->
A) dimensions of full size rectangle are width 15 and length 18
dimensions of reduced size rectangle are width 15 and length 16
B) full size: 15*18=10*18+5*18=180+90=270cm^2
reduced size: 15*16=10*16+5*16=160+80=240cm^2
Given:
At the store a cell phone cost 1.1 times as much as it sells online.
The cost of it is $888.98 online.
To find:
How much more does it cost from the store?
Solution:
It is given that,
Cost of a cell phone online = $888.98
At the store a cell phone cost 1.1 times as much as it sells online. So, cost of the cell phone at store is
The cost of cell phone at store is $977.878
.
The difference between the cost of cell phone at store and online is
Therefore, the cell phone cost is $88.898 much more at the store.
