Answer:
The more expensive book cost $90, the other two combined cost $60.
Step-by-step explanation:
x = cost of more expensive book
y = subtotal cost of the other books
x = 50% more than y, so x = 1.50y = 1.5y
x + y = total cost = $150
1.5y + y = 150
y = 150/2.5 = 60
x = 1.5y = 1.5(60) = 90
Answer:
32 units squared
Step-by-step explanation:
This is kind of a weird shape, so split it into smaller shapes, in this case two triangles and a rectangle.
Both of the triangles have a base of 8 and a height of 2. Multiply the base and the height together, then divide by 2. 8*2/2 equals 8, so the area of each triangle is 8.
For the rectangle, the length is 2, and the width is 8. Multiply the length and the width together to get 16.
Finally, add the areas of all those smaller shapes together to get the area of the whole shape, 32 units squared.
