Adding the tax?
to add taxes it requires only two steps:
1) multiply the price by the tax as a Decimal (tax must be in decimal form)
2) add what you get after multiplying to the original price
So..
1) 49.95(.05) = 2.497
2) 49.95+ 2.497 = 52.447 round to 52.45
So the whole price is $52.45
**you can also round the 49.95 to 50 before doing the math to make it easier**
Multipl .365 by 100 and you get 36.5%
Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
