Answer: To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
Step-by-step explanation:
That is the correct graph that represents
{3y≥x−9 3x+y>−3

They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
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.
