A doctor is using an experimental treatment for a patient of his who has liver cancer. The treat involves the usage of a radioactive compound, referred to as Compound X. The treat works by embedding micro-gram dosages of Compound X insides microscopic ceramic beads. The beads are put into solution and injected straight into the tumor. Beads block blood to the tumor and slowly kill it by radiation. If the patient is injected with 89 mg of the radioactive substance, and if the substance loses 1/88 of its mass every hour, write an exponential equation of the form m(t) = A 6-t Then, determine the amount of time it takes for half of the mass to be lost (half-life). show work please ​

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
