Answer:
$136.50
Step-by-step explanation:
100 - 12 = 88% (How much percentage of money the student left)
88% = 120.12
1% = 120.12 ÷ 88 = 1.365
Before buying the book, the student had 100%
100% = 1.365 x 100 = 136.50
Answer:
-3
Step-by-step explanation:
The number 4 is the plotted point on the y-axis, meaning the next point would be located down 3 and right 1 (-3 over 1) and so on. The rise over run is the m in y=mx+b<em>. </em>
This is how the whole equation goes:
1/x^-a = x^a
So, 1/5^-2 is the same as 5^2, which is 25.
