Answer: 89.1
Step-by-step explanation: Firstly, for the square, you would multiply 8 by 8 which would result in 64. That is your first addend. Next, to find the area of the semicircle, you find the area of a whole circle, then divide by two. In this case, the area formula would be (pi)r^2. So, the radius would be 4, and in he formula that would end up with the answer being 50.24. Then, you divide by two. 25.1 (rounded to tenths) + 64 = 89.1.

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