Current # of albums ÷ % = original total number of albums
=80 ÷ 48%
=80 ÷ 0.48
=166.66
***BUT since you cannot have a partial album, you need to round up to 167.
Hope this helps! :)

Answer:
$47
Step-by-step explanation:
Create a system of equations where s is the cost of a shirt and t is the cost of a tie:
s + t = 64
s = t + 30
Solve by substitution by substituting (t + 30) into the first equation as s:
s + t = 64
(t + 30) + t = 64
Add like terms and solve for t:
2t + 30 = 64
2t = 34
t = 17
Then, plug in 17 as t into one of the equations to find s:
s = t + 30
s = 17 + 30
s = 47
So, the cost of the shirt is $47
For factorisation it is necessary that you multiply the last and first values
Here we can see : we require 27a^2
SO if we multiply the answer should be 27 and if we add the answer should be 28 ....here goes !!
a^2 + 28a + 27
a^2 + 27a + 1a + 27
Here we can see : I we multiply 27 and 1 the answer will be 27a^2 but if we add 27 and 1 as shown then answer will be 28a:
a ( a + 27 ) + 1 ( a + 27 )
( a + 1 ) × (a + 27 )
