Answer:
44.040192
Step-by-step explanation:
I barely remember doing this in math. I did some research on the question and that's the answer that I got. If I'm not wrong, the formula you are supposed to use is:
y = a(r)^t
A being the regular number in the problem (210).
R is the rate/ ratio (8% which would be converted to 0.8).
T is the time (7 years).
Put the equation together, and you get y = 210(0.8)^7. When you plug it into a calculator, you get 44.040192.
Sorry for the long explanation, but I hope this helps you solve your problem!
