Answer:
Mandy's bag is 60% heavyer than Donna's.
Step-by-step explanation:
When someone's bag is "x%" heavyer then someone else's it's the same as saying that it is "100% + x%" of that value, while if it is lighter it's the same as saying that it is "100% - x%".
Since Mandy's bag is 20% heavier than Kathleen's, then:
Mandy = 1.2*Kathleen
Since Donna's bag is 25% lighter than Kathleen's, then:
Donna = 0.75*Kathleen
Kathleen = Donna/0.75
Then
Mandy = 1.2*(Donna/0.75) = 1.6*Donna

Answer:
Formula for area of triangle:
A = bh x 1/2
Formula for area of parallelogram:
A = bh
Now find the area of the figure above which is a triangle:
3(base) x 8(height) x 1/2 = <em>12</em>
Let's find the area of the parallelogram;
6(height) x 9(base) = <em>54</em>
Add the two areas together:
12 + 54 = 66 cm2
