The algebraic expression is [tex]22 ( 1 - 0.01y)[/tex].
We have given that decrease 22 by y%.
we need to calculate what is y% of 22. y% of 22 means y% into 22
y% x 22
= 0.01(y) x 22
= 0.22y
Therefore the 0.22 y is y% of 22.
Now we have to decrease 22 by its y% which can be written as,
What is the meaning of decreasing percentage?
Loss of value from the given quantity is nothing but the decrease in percentage
We have given that 22 decreased by y%
Therefore we get,
22 - y% of 22
use the value of y% so we get,
[tex]= 22 - 0.22y.......(1)[/tex]
The simplified form of expression is
factor out 22 from (1) so we get,
[tex]22 ( 1 - 0.01y)[/tex]
Therefore,the algebraic expression in term of y is [tex]22 ( 1 - 0.01y)[/tex].
