The correct answer is:
Matthew's rate is higher by $50 per month.
Step-by-step explanation:
We know that Christopher's rate is $550 per month.
To find Matthew's rate, we will treat the data we have as ordered pairs:
(3, 1800)
(6, 3600)
(9, 5400)
We find the slope of the line between these points. The formula for slope is:
Using the first two points, we have:
To verify Matthew saves the same amount each month, we will find the slope between the second two points and make sure they're the same:
Matthew's rate is $600 per month.
This is higher than Christopher's by 600-550=$50 per month.
-4x-7 also in case you want to know
7= -4x
x= -4/7
Using the order of operations (PEMDAS)...
23 · 1 - 1 = ?
23 - 1 = ?
22
The answer is 22
