Step-by-step explanation:
The solution for a system of equations will be when the graphs touch each other, or intersect, and that happens when both equations equate each other, so, let's do so,
Answer:
75 seconds
Step-by-step explanation:
Here, we want to get her time 6 weeks ago.
We shall have an exponential model to link this all up
The exponential model would look like;
y = I(1 - r)^n
where y is the present time
I is the initial time she started with which we are calculating
r is the rate of change which is 2% = 2/100 = 0.02
n is the week number which is 6 in this case
So we have;
66 = I(1 - 0.02)^6
66 = I(0.98)^6
I = 66/0.8858
I = 74.5 seconds
This is approximately 75 seconds
Her time 6 weeks ago is 75 seconds
