Answer:
D= 10 Dollars each month
Step-by-step explanation:
You find this answer by subtracting the one time fee of 20 from the total payed of 70, leaving you with 50. You then divide that 50$ by 5 months.
8 and 12 are separated by 1 line, and they have a difference of 4 units, so..
count every two lines and add 4 units
this means that the blue dot is 20
X - 0.17 = y
add 0.17 to both sides
x = y + 0.17
The answer is a or d i’m not sure which one though sorry.
