4w -1
Because 7w + -3w = 4w and then -6 + 5 = -1
Calculation for plan A:
Let numbe of months = x
Given that $10 is the monthly fee.
Given that $150 is the joining fee.
Then cost equation for plan A is given by:
A=10x+150
Calculation for plan B:
Let numbe of months = x
Given that $30 is the monthly fee.
Given that $50 is the joining fee.
Then cost equation for plan B is given by:
B=30x+50
Now we have to find on what month will the cumulative costs of the plans be equal.
So we will just set both equations equal to each other
10x+150=30x+50
150-50=30x-10x
100=20x
5=x
Hence it will take 5 months to make cost of both plans equal.
To find the total cost plug x=5 into any of above equations:
A=10x+150=10*5+150=50+150=200
Hence final cost will be $200.

Answer:
B = 5:00
Step-by-step explanation:
360/12 = every hour is 30 degrees more
150/30 = 5 hours
