Initial cost = $126
Final cost = $150
Then
Amount of change = (150 - 126) dollars
= 24 dollars
Then
Percentage change = (24/126) * 100
= 2400/126 percent
= 19.05 percent
So from the above deduction we can easily conclude that the percentage change is 19.05%. I hope the procedure is simple enough for you to easily understand. You can generally use this method for solving similar kind of problems in future without requiring any kind of help from outside.

we know that
A quick way to estimate the sum of two numbers is to round each number and then add the rounded numbers
case a) We round the number to the nearest hundred
so
Round up is equal to 
Round up is equal to 
Find the estimate sum

case b) We round the number to the nearest tens
so
Round up is equal to 
Round down is equal to 
Find the estimate sum

Answer:
3150
Step-by-step explanation:
Total price is 3500.
10% discount on 3500 will be:
(10/100)*3500=350
We get a discount of 350 so we will pay 3500-350 which is 3150.
