T(n)=t(0)xR to the n power since the sequence is geometric
t(0)=1.5 because 1.5x2=3
R=2
Answer:
Step-by-step explanation:
Plot the points x-intercept and intercept on the graph. Join the two points to get the straight line. This is the graph of the linear equation.
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
