You need to find 7 1/2% of $29.95.
To do that, just multiply the percent by the number.
7 1/2% * $29.95 =
= 7.5% * $29.95
= 0.075 * $29.95
= $2.24625
The answer is $2.25
15% of $35 is 5.25. 35- 5.25 = $29.75
What you want to do is change the variable positions of X and Y
So it would be a new equation of
x = 1/2y + 3
Then you would need Y to be by itself so you solve for that
x-3 = 1/2 y
then,
2(x-3) = y
Your inverse function is 2(x-3) = y
Hope this helped :D
