Answer:
A=18 because 6+18 (was 6+a) is 24 - 11 = 13
Step-by-step explanation:
A=18
3 laps because the track is 1/8 mile because when she ran 8 laps it is 8/8 which = 1 so the answer is 3 laps
Step-by-step explanation:
Total ratio=4+11
=15
1st friend's share
= 4/15 x 150
=4 x 10
=£40
2nd friend's share
=11/15 x 150
=11 x 10
=£110
The exponential model would take the form:

A, the initial value is 2, we will use 3 days and 8 tops to find k, or the rate.


Now, plugging in 6 days:


The linear would take the form:
y = mx+b
First the slope would be: (8-2)/(3-1) = 3
And to find b we could plug in the point (8,3):
8 = 3(3)+b
b = 8-9
b = -1
y = 3x-1
At x=6
y = 3(6)-1
y = 17
Thus, the exponential is almost double the result of the linear! Hope that helps.
