Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is <em>x</em> percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is <em>discounted. </em>If it's now selling for 70%, it has been discounted 30%. So the answer is 30%
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.
