more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90

I think true im sorry if its not
The question is asking for the circumference
The equation for circumference is C=2(Pi)r<span>
</span>to find the radius, half the diameter 4/2=2
the equation is now C=2(Pi)2<span>
simplify the equation...
C=4(Pi)
Pi is </span>3.1415926535897932384626433832795
Now multiply 3.1415926535897932384626433832795 times 4 = 12.566370614359172953850573533118
Round to nearest tenth...

Percent decrease. 41%
percent change= (new-old)/old *100
= -41 % the negative means decreasing
Let the common multiple be x
3x : 2x
3x = 125
x = 125/3
So, B pays 2x = 2 × 125/3 = £250/3
