Answer:
11
Step-by-step explanation:
When increasing a percentage I usually just turn the percentage to a decimal. So, let's say you have 100 gallons of gas and it'll get an increase by 20%, just multiply 100 by .20 and you'll get 20, then add 20 to 100 to see what you'll have after. In this case, 15% would be .15, just multiply 22 by .15 to see how much the increase is, then add what you get to 22.
The answer to a multiplication problem is called a product
Answer:
Step-by-step explanation:
If a polynomial p(x) is divided by a factor (x + h ) then the remainder is
f(- h)
Here p(x)is divided by (x - 
) thus evaluate p( ) for remainder
p( )
= ( )³ - 2( )² + 8
= 
- + 8
=
Let us say the price of a table is 
and a price of a chair 
. Using this terminology we can say that the cost of 2 chairs and 5 tables is 
. We have a second equation though, 
from a table being 30 more than the price of a chair. Using this we can solve the system of equations. I think substitution is the quickest way to do this. Plug x from our second equation into the first equation.
This will simplify to the price of a chair is Rs 320. And add Rs 30 to that and we can find that the price of a table is Rs 350.
It is always good to check. So go ahead and check 
to see that the first equation works (we know the second equation works just by eyeballing. And it looks like the cost is Rs 2300! Hooray!
