Answer:
A 50% increase
Step-by-step explanation:
Area = length x breadth
Let illustrate this with an example
original dimensions
length = 4
breadth = 5
area = 4 x 5 = 20
new dimensions
length = 4/2 = 2
breadth = 5 x 3 = 15
area = 15 x 2 = 30
Percentage change = 30 - 20 / 20 x 100 = 50%
Answer:
Yea that problem is a bit confusing,
2y should be double of what y is, which is 4x+5

I feel bad cause I am sure the teacher is wrong on this, he/she had probably made a typo, or you made a typo, but that's ok! We all make typos!

Answer:
$300 was the regular price of the sofa.
Step-by-step explanation:
If $219 is 27% less than the regular price, then it represents 73% of the regular price.
Regular price = r.
r/1 x 73/100 = $219. Reverse this to find that $219/1 divided by 73/100 = r.
To divide fractions, reverse the second fraction and MULTIPLY:
$219/1 x 100/73 = 21900/73 = 300.
