Using proportions, it is found that 68 more people prefer vanilla than do strawberry.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, it is found that, out of 400 people:
- 18% preferred strawberry.
Hence the amounts are:
The difference is:
140 - 72 = 68.

3p-4=8
+4 on both sides to get
3p=12
divide each side by 3 to get p=4
2p=4
divide off 2 on both sides to get
p=2
Is 2=4? If it is then it is equivelent, if it isnt then theyre not.
Answer:
(2x - 2) (4x +4)
= 2x*4x + 2x*4 - 2*4x - 2*4
= 8x^2 + 8x - 8x - 8
= 8x^2 - 8
Your answer is correct. Great.
