Answer:
9 steps
Step-by-step explanation:
Let
be the number of jumps
and
be the number of steps
So the first case
![2x+13y](https://tex.z-dn.net/?f=2x%2B13y)
Second case
![4x-5y](https://tex.z-dn.net/?f=4x-5y)
Both cover equal distances so
![2x+13y=4x-5y](https://tex.z-dn.net/?f=2x%2B13y%3D4x-5y)
![\Rightarrow 2x-4x=-5y-13y](https://tex.z-dn.net/?f=%5CRightarrow%202x-4x%3D-5y-13y)
![\Rightarrow 2x=18y](https://tex.z-dn.net/?f=%5CRightarrow%202x%3D18y)
![\Rightarrow x=9y](https://tex.z-dn.net/?f=%5CRightarrow%20x%3D9y)
So, one jumps is 9 steps.

Answer:
22
Step-by-step explanation:
Solve the inequality (20 + 0.5x) + 0.15(20 + 0.5x) ≤ $62.10 for x:
20 + .5x + 3 + 0.75x ≤ 62.10
Combining the x terms, we get:
20 + 3 + 1.25x ≤ 62.10.
Combining the constants on the left:
23 + 1.75x ≤ 62.10
Combining the constants:
1.75x = 39.10
Solving for x: 39.10/1.75 = 22.34
Thus, the max number of whole pages she can have in her book is 22.
We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.
36.72/x = 85/100
Solve for x.
x=36.72/0.85
x=43.2
So, the bill was $43.20 before applying the voucher discount of 15% off.
