Answer: Choice A
----------------------------------
The first term is 8 as this is the y coordinate of the point when x = 1.
The second term is 4 (since y = 4 when x = 2)
etc etc
The sequence of terms is: 8, 4, 2, 1, ...
Each time we're dividing by 2, or multiplying by 1/2. This is why r = 1/2
Put this together and we have this geometric nth term formula
an = 8*(1/2)^(n-1)
This means the answer could be A or it could be C. However, we can rule out choice C because the rate of change is not positive. Draw a line through (1,8) and (3,2) and you'll see this line has a negative slope. So the rate of change is negative.
The only answer left is choice A.

Answer:
$40.20
Step-by-step explanation:
$7.50 per hour. Tim worked for 2 hours so you would do 2 timez 7.5 which is $15, the total he earned from mowing.
$6.30 per hour. Tim worked for 4 hours so you would do 4 times 6.3 which is $25.2, the total he earned from washing windows.
To get the total of how much he earned all together you add 15 and 25.2 and you get $40.2.
