Answer:14%
Step-by-step explanation:
final grade score=a
20% of a=15
20/100 x a=15
20a/100=15
Cross multiply
20a=15 x 100
20a=1500
Divide both sides by 20
20a/20=1500/20
a=75
B% of 75=10.5
B/100 x 75=10.5
75B/100=10.5
Cross multiply
75B=10.5 x 100
75B=1050
Divide both sides by 75
75B/75=1050/75
B=14
Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
