HELP: I need help with the mathematical expression of this question. I've tried everything and I even looked at examples but I still can't figure it out. Any help is appreciated, thanks!

Step-by-step explanation:

A = P (1 + r)^n

where A is the final amount,

P is the initial amount,

r is the rate of change per cycle,

and n is the number of cycles.

The rate of change is -20% per 10 minutes.  The initial amount is 550 grams.

A = 550 (1 − 0.20)^(t/10)

A = 550 (0.8)^(t/10)

After 55 minutes, there is approximately 161 grams of salt.

show us the graphs dude
