Answer: A decrease of 77.77%. So the <em>first </em>option.
Answer:
A decrease of 3.5%
Step-by-step explanation:
since 36-8 is 28, it went down a bit so it would be 3.5%
180
k = 3
v = 60
(Found v by dividing any of the top numbers by the bottom number, ex: 420/7 = 60)
3k = 3(60)
3k = 180
115 = 10X + 0.25(60)
115 = 10x +15 (this is the equation to use)
100=10x
x=10 hours
Option 3
When it says 12 less, that means -12.
