Answer 5

You are welcome.

Answer 6

Total cost equal:
74.8m = 298.9+68.7m
-> 74.8m - 68.7m = $289.9
Number of months:
=> m = $ 289.9 / 6.1 = ~29 months

Answer 7

I dont think Chlorophyll is correct.

Use A for the cost after, and B for months.

A=289.9+68.7B

A=68.7

289.9+38.7b=74.8b

6.1b=298.9

b=49
