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 value of y when the value of x is 8 is 87
<h3>Function and values</h3>
Functions are equation expressed in terms of variables. Given the expression below;
y = 10x + 7
If the value of x is 8, then on substituting, we will have:
y = 10(8) + 7
y = 80 + 7
Simplify
y = 87
Hence the value of y when the value of x is 8 is 87
