You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.
Amount of purchase that Steve made = $40
Percentage of tax that Steve needs to pay = 10%
Then
Amount of tax that Steve needs to pay for the purchase = (10/100) * 40
= 1 * 4 dollars
= 4 dollars
Then
The total amount including tax
that Steve needs to pay for the purchase = (40 + 4) dollars
= 44 dollars
So the dollar amount of tax that Steve had to pay is $4 and
the total amount that Steve had to pay was $44.

The output would be -9.
If you substitute -10 in for x, the equation becomes:
Y = (3/2)(-10) + 6.
First solve for (-3/2)(10).
(-3/2)(10) = -15.
This is negative because a negative number multiplied by a positive number will equal a negative number.
Then add 6 to -15.
-15 + 6 = -9.
Therefore, when the input is -10, the output is -9.
