The equation that models the sequence is: 6+6 each time.
Hi!
The fully factored form of this equation is (3x+2)²
Let x be the month on which the fee for two plans are equal.
Therefore,
150 + 10x = 50 + 30x
10x - 30x = 50 - 150
-20x = -100
x = 5
Cumulative cost = 150 + 10(5)
= 150 + 50
= 200
Hence, Karan will pay a cumulative cost of $200 dollars with either plan to go to the gym for 5 months.
Step-by-step explanation:
2x²-4x=0
2x²=4x
2x=4
x=2
