x ≤ 7
Step-by-step explanation:
Let the cost of each book be $2
Let the amount of book she can buy be x
If she can spend no more than $15
Amount of book she can buy≤ Total amount/cost of each book
Amount of book she can buy ≤ $15/$2

Answer:
(n x -5) - 2
Step-by-step explanation:
V=hpir^2
r=10
v=6283
6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches
