Answer:
2%
Step-by-step explanation:
20% takes 10 years to decay
To find per year decay, we divide the percentage by the number of years, so we get unit rate of years {per year]. Thus we have:
20%/10 = 2% per year
It's that simple.
Hence, the percentage by which the substance decays each year is 2%
Step-by-step explanation:
x intercept is at y=0
2x= 12.4
x = 6.2
y intervept is at x=0
4y= 12.4
y = 3.1
