Set up proportion 170/180=x/1 than cross multiply 170x=180 divide both sides by 170 answer 0.944 so 94% remains
Answer:
⇒ 
[Factorized form]
Step-by-step explanation:
Given expression:
We need to make 
the subject.
In order to do that we need to solve the expression for in terms of 
and 
We have,
Subtracting both sides by 
Taking square root both sides in order to remove square of
The difference of squares can be factorized and written as:
[difference of squares 
]
f(-4) = 3(-4)^2 - 2(-4)
f(-4) = 3(16) + 8
f(-4) = 48 + 8
f(-4) = 56
I think the answer is 56 :)

So,
If you do some simple division, you will find how much each cm costs in each cake.
20cm cake = 67.5 cents/cm
25cm cake = 93.75 cents/cm
Assuming that you cannot order fractions of cakes, the best deal would be to order 5 of the 20cm cakes.
Cost = 13.50 * 5 = $67.50
You will have to pay $67.50 for the cakes if you want the best deal.
