Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease
Slope: 0.500/2.000 = 0.250
x: 32/1 = 32.00000
y: -32/4 = -8
Answer:
time spent reading science fiction= 18
time spent reading non-fiction=102
Step-by-step explanation:
15 percent off 120.00 is 102.00 The difference is 18.00
X-12=20
x=20+12
x=32
answer is 32
