Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
I think the correct answer would be C.
Step-by-step explanation:
y= 1
when x=2
here
when x= 3
y=4
There will be 4 rows and 3 in each row. one more cube will be placed at the bottom.
hope it helps!
