There should be a total of 3 zeros because the largest exponent is 3.
Use the exponential function of f(x)= 100x times (1.08)^2
If you have 20/10, that equals 2. Then if you move the decimal place over 1 place then you have 2. If you divide 2 again by 10, then move the decimal place over in another place, it is equaling 0.2.
Add 110 to both sides so you get -240
then divide it by 16 so you get x = -15
Check
-350 = -110+16(-15)
-350 = -110 - 240
-350 = -350
