The equation to solving this is 90/40 = 88 / X
knowing this I multiply 40 and 88 and 90 and x. I got 3520 and 90x. Now I divide 3520 by 90 and I get 39 and 1/9. So the time for the sample to decay is:
39 1/9 years.
Couldn't figure out how to type this out so here's a picture of the thought process.
Answer:
the answer is 11 years
Step-by-step explanation:
if school A is graduated 50/years,
the graduated in 11 years is 550
added of graduated 1,700 in 550 is 2,250
if school B is graduated 150/years,
the graduated in 11 years is 1650
added of graduated 600 in 1650 is 2,250
so School A and B is to be equal in 11 years
Its nonlinear decreasing.
hope this helps you
