Answer:$27
Step-by-step explanation:
cost price(cp)=$36
Percentage off=25
sale price=sp
Percentage off=(cp-sp)/cp x 100
25=(36-sp)/36 x 100
Cross multiplying we get
25x36=100(36-sp)
900=100(36-sp)
Divide both sides by 100 we get
900/100=100(36-sp)/100
9=36-sp
Collect like terms
sp=36-9
sp=27

Answer:
There are plenty of numbers that can multiply with 28 to create a perfect square.
The smallest perfect square could be created as following:
We have: 28 = 4 x 7 = 2^2 x 7 (2 and 7 are prime numbers).
=> Another 7 is left to create a perfect square.
=> The smallest one among possible solutions is 7
Check:
28 x 7 = 196 = 16^2 (valid)
Hope this helps!
