Answer:
f(x)=197(1.0257)^7x
Step-by-step explanation:
f(x)=197(1.25)x
To make this simpler when we manipulate, we will write it as:
f(x)=197(1+0.25)x
Now since that's the rate for a week, the daily rate of increase is 25% distributed over 7 days, right? Hence the new rate is 0.25/7=0.036. And since that's for a day, the power would be 7 TIMES every time the rate is compounded.
f(x)=197(1+0.257)^7x
or f(x)=197(1.0257)^7x
